Therefore, tumors within these tissue types can be selectively targeted by creating drug delivery nanostructures greater than the intercellular gap of the healthy tissue but smaller than the pores found within the tumor vasculature.
Through precise control of the drug carrier architecture, the release of the drug can be tuned to achieve a desired kinetic profile. Three of the most common kinetic profiles are zero order, first order, and Higuchi; these are depicted in figure 1 and expressed mathematically in the following equations. The delivery of most drugs is accomplished through oral administration or by injection and follows firstorder kinetics. The ideal release profile for most drugs would follow a steady release rate so that the drug levels in the body remain constant while the drug is being administered.
More recent transdermal drug delivery mechanisms follow the Higuchi model As shown subsequently, nanostructured polymeric and silica nanoparticles are being developed as drug carriers which achieve near zeroorder kinetics. Various nanoscale architectures can be realized including solid spheres, hollow spheres, tubes, porous particles, solid particles, and branched structures. To achieve such nanostructures, different fabrication methods are used depending on the type of material. The methods used for nanoscale assembly include molecular self-assembly 30 , bio aggregation 31 , nanomani- pulation 32 , photochemical patterning 33 , molecular imprinting 33 , layer-by-layer electrostatic deposition 34 35 , and vapor deposition With current liposome technologies it is not difficult to transfect a cell for purposes of gene therapy, but the therapeutic gene may be degraded if it is not able to traffic out of the endosome.
To enhance the efficacy of gene therapy, synthetic pH-sensitive histidylated oligolysine can be added to a drug-liposome complex to aid in escaping from the endosome This protocol was shown to improve the transfection efficiency in prostate and pancreatic cancer cell lines by 39 mfold, and elevated the expression of the transgene in a human prostate cancer xenograft model in athymic nude mice without increasing toxicity. Monoclonal antibodies are good targeting vehicles for nanoparticles but other bio conjugates are being tested with varying degrees of success.
Nucleic acid ligands called aptamers that mimic antibodies are potential replacements because they can be designed to bind to practically any antigen in an in vitro system. The aptamers are generated by evolutionary methods in vitro, and the molecules with high affinity are used for targeting antigens in vivo. This strategy has been applied to directing PEG-coated nanoparticles to home in on prostate-specific membrane antigen in prostate cancer cells. The aptamer conjugated particles were shown to have a fold increase in binding versus the control particles, and a large increase in uptake of drugencapsulated particles There are numerous examples of similar type targeting of nanoparticles 5 13 39 40 41 , and this area of research promises to provide important weapons in the arsenal for developing a cure for cancer.
One of the ultimate goals of nanotechnology is to create medically useful nanodevices that can function inside the body. It is envisioned that nanodevices will be hybrids of biologic molecules and synthetic polymers that can enter cells and the organelles to interact directly with DNA and proteins Additionally, nanomedicine will have an impact on the key challenges in cancer therapy: localized drug delivery and specific targeting. Among the newly developed nanomedicine and nanodevices such as quantum dots, nanowires, nanotubes, nanocantilevers, and nanopores, nanoshells and nanoparticles are the most promising applications for various cancer treatments.
The gold nanoshell-antibody complex can be used to ablate breast cancer cells. Nanoshells 43 have a core of silica and a metal outer layer. They can preferentially concentrate in cancer lesion sites through enhanced permeation retention. A nearinfrared laser illuminates the tissue, and the light will be absorbed by the nanoshells to generate an intense heat that destroys only the cancer cells without damaging the surrounding healthy cells Nanoparticles have already been used for targeted drug delivery, which enables much earlier detection 45 and immediate treatment of cancer.
Nanoparticles attached to chemotherapeutic drugs allow them to traverse the blood-brain barrier for brain tumor treatment In January , a nanoparticle-based drug called Abraxane paclitaxel protein- bound particles, Abraxis Oncology was approved by the Food and Drug Administration for breast cancer treatment. Abraxane uses nanoscaled particles of the natural protein albumin that can be delivered in the body without the use of solvents.
Biodegradable polymer nanoparticles, typically consisting of polylactic acid PLA , polyglycolic acid PGA , or a copolymer of PLA and PGA, are being investigated for the delivery of proteins and genes 48 49 , vaccines 50 51 and anticancer drugs 52 13 Dendrimers , a unique class of polymers, are highly branched macromolecules whose size and shape can be precisely controlled 54 Dendrimers are fabricated from monomers using either convergent or divergent step-growth polymerization.
Two representations of polyamidoamine-based Dendrimers are shown in figure 2. The well-defined structure, monodispersity of size, surface functionalization capability, and stability are properties of dendrimers that make them attractive drug carrier candidates. Drug molecules can be incorporated into dendrimers via either complexation or encapsulation as shown in figure 3. Dendrimers are being investigated for both drug and gene delivery 56 57 , as carriers for penicillin 58 59 , and for use in anticancer therapy 60 Dendrimers used in drug delivery studies typically incorporate one or more of the following polymers: polyamidoamine PAMAM 62 63 , melamine 64 , poly L-glutamic acid PG 65 , polyethyleneimine PEI 65 , poly propylene imine 66 , and poly ethylene glycol PEG Chitin and chitosan have also been incorporated with dendrimers The most commonly investigated siliconbased materials for drug delivery are porous silicon and silica, or silicon dioxide.
Architectures include calcified nanopores, platinum- containing nanopores, porous nanoparticles, and nanoneedles 69 The density and diameter of the nanopores can be accurately controlled to achieve a constant drug delivery rate through the pores. Porous hollow silica nanoparticles PHSNP are fabricated in a suspension containing sacrificial nanoscale templates such as calcium carbonate Silica precursors, such as sodium silicate, are added into the suspension, which is then dried and calcinated creating a core of the template material coated with a porous silica shell.
The template material is then dissolved in a wet etch bath, leaving behind the porous silica shell. Creation of drug carriers involves the mixing of the PHSNPs with the drug molecule and subsequently drying the mixture to coalesce the drug molecules to the surface of the silica nanoparticles Through controlling the pore size and the particle diameter, the release kinetics approach near zeroorder, where the release behavior of conventional silica nanoparticles is compared with that of porous hollow silica nanoparticles. As shown, the porous hollow nanoparticles exhibit a much more desirable gradual release Examples of therapies being investigated for use with silicon-based delivery systems include porous silicon embedded with platinum as an antitumor agent 73 , calcified porous silicon designed as an artificial growth factor 74 , silicon nanopores for antibody delivery 70 75 and porous silica nanoparticles containing antibiotics 71 , enzymes 76 and DNA Typical fabrication methods involve templating of the thin metal shell around a core material such as a silica nanoparticle.
Typical metals include gold, silver, platinum, and palladium. When linked to or embedded within polymeric drug carriers, metal nanoparticles can be used as thermal release triggers when irradiated with infrared light or excited by an alternating magnetic field Bimolecular conjugation methods of metals include bifunctional linkages, lipophilic interaction, silanization, electrostatic attraction, and nanobead interactions For example, the most widely used and effective drug, the common aspirin, is only about 0.
Many of the globular proteins, such as hemoglobin, are 5 nm in diameter, and natural proteins of similar size may be used as a therapeutic.
Double-stranded DNA in the nucleus is about 2. Medicinal and structural chemists have been creating and manipulating nanometer and sub nanometer sized components of drugs for decades, and will continue to do so into the foreseeable future. The difference is that they will now be joined by a wide variety of scientists from a number of disciplines normally not involved in drug research. What are the requirements for an effective and safe cancer drug 85? There must be an adequate drug concentration in the body to allow for an effective dose at the tumor site.
The drug must have a high differential toxicity toward the tumor or a favorable therapeutic window. Research in nanomedicine will be addressing all these points, and a few examples in the drug development arena will be given below. Monoclonal antibodies will be an essential component of the new wave of cancer treatments developed through nanotechnologies.
They are being used as imaging vehicles, for drug targeting, as drug carriers, and as the drug itself. There are 9 or more FDA-approved antibodies approved for clinical use in cancer 86 87 88 , and many more are being evaluated in clinical trials.
The mechanism of action of the antibodies includes receptor ligand binding competition; interference with receptor function; antibody-dependent, cell-mediated cytoxicity; complement-dependent cellular cytoxicity; or, perhaps, a combination of the above. This activity can also be combined with toxins directed at the cancer cell to produce an even more efficacious drug. One of the holy grails of drug research is to be able to rationally design and produce effective smallmolecule inhibitors of protein function 89 90 91 92 93 94 Development of many drugs will be the result of application of nanotechnologies that have been in place for many years.
For example, nuclear magnetic resonance and x-ray crystal structures of target proteins and their ligands or substrates are being used as the template for rational design of new drugs. The target may be enzymes or receptor—ligand proteins. Inhibitors of enzymatic activity are, in general, easier to design than blockers of protein— protein interactions. In many patients, administration of the drug results in what appears to be complete remission, but Gleevec-resistant leukemia often returns through mutations in the active site.
By careful study of the mutations and the structure of the kinase, new small molecular inhibitors were designed that could block the mutant strains and appear to be more efficacious than the original drug 98 99 The two drugs are reported to work synergistically, which will, hopefully, result in a complete cure of chronic myeloid leukemia. Drugs derived from nucleic acids are beginning to make an impact on the nanomedicine scene. Antisense technology exploits the use of oligonucleotides in the range of 15 to 20 nucleotides to block the function of an RNA target.
This technology has made rapid progress after experiencing initial difficulties in showing efficacy for in vivo models of disease. Ongoing clinical trials using antisense drugs include prostate, breast, pancreatic, lung, colorectal, melanoma, and brain cancers.

A novel approach for this technology is to use oligonucleotides for sensitizing tumor cells to chemotherapy. The oligonucleotides are being combined with Nano liposomes to target and deliver the nucleic acids to the cancer cells and block production of the alpha folate receptor. This block was shown to decrease cell survival of breast cancer cell lines, and sensitized a cell line by 5-fold to doxorubicin.
This is a good example of how nanotechnologies can be used to increase the effectiveness of existing drugs, facilitating the use of lower dosages to decrease toxicity. The siRNAs are small doublestranded molecules of about 21 nucleotides in length that result in specific degradation of mRNAs containing the complementary sequence. This specificity makes siRNAs attractive candidates as nanodrugs for blocking the expression of wayward genes in cancer, but their application can be hindered by instability in the blood and poor uptake into the target cells.
To overcome these problems, siRNA has been complexed with nanoparticles containing a homing sequence that directs the complex to the tumor site A fascinating approach for eradicating tumors is through the application of cancer immunotherapy or vaccines It is thought that the body can eliminate small tumors by an appropriate immune response, but at some point a malignant cancer is able to evade the response by developing mechanisms that blind the host to its presence.
If methods can be found to activate the immune system against these tumors, the body should be able to destroy the cancer, and all forms of cancer might be susceptible to this type of immunotherapy. Tumor antigens by themselves are not very immunogenic and require some type of adjuvant to boost the immune response against the cancer. A new vaccine design has been developed that couples the antigens to solid-core nanobeads For effectiveness, the beads have to be of narrowly defined size 40 nm to 50 nm , which allows them to localize to dendritic cells in the draining lymph nodes. Conjugation of the antigens to the nanobeads induced responses that were 2 to 10 fold higher than other bead sizes, and higher than currently used immunizing adjuvants were tested.
A single dose of the antigen-coated beads protected mice from tumors in 2 different model challenges, and was even able to cause rapid clearance of established tumors. This is a good example of how nanotechnologies may provide a major breakthrough in cancer therapy and the effectiveness of vaccines in general.
Cancer immunotherapy may provide a relatively benign, nonchemotherapeutic method of destroying tumors. Another promising and, perhaps, complementary approach is the thermal ablation method of tumor destruction. Treatment of solid tumors with hyperthermia has been an option for some time , but has some drawbacks.
For deep, underlying tumors, the energy source can harm the intervening and surrounding healthy tissue even when focused beam are used. To overcome this problem methods have been developed to selectively heat the tumors using near-infrared—absorbing gold nanoparticles called nanoshells Nanoshells, in this case, are composed of a silica core surrounded by a thin gold metal shell, and will absorb energy heat up when exposed to the appropriate wavelength of light.
The near-infrared characteristics were chosen because absorption by tissues is minimal and penetration of the light is optimal at this wavelength. The nanoshells were injected into mice, and the nanoparticles were simply allowed to accumulate in implanted tumors. The tumors are then illuminated with a near infrared diode laser to heat the tumor and cause cellular destruction. By this protocol all the tumors were ablated, and the mice remained tumor-free for many months.
Although not used in these studies, the efficacy of the procedure could be improved by attachment of tumor homing or -targeting molecules to the Nano shells for increasing concentration at the site of heating. In appropriate settings, thermal ablation methods could be used to replace surgical resection of tumors, and targeted therapies and immunotherapy as a substitute for toxic chemotherapy. SUMMARY If the incidence of deaths from cancer had dropped as much as heart disease, cancer would be approaching the status of a rare disease.
Instead, overall cancer mortality has changed little during the last decade, while deaths from heart disease have plummeted almost by half. Although cancer may be more complex than cardiovascular disease, it is not inconceivable that lifestyle changes smoking cessation and new drugs developed from Nano technological and other medical advances could create the same laudable statistic for cancer as heart disease in the next decade.
Nano technological studies are not new. In essence, all drug molecules can be considered as Nano engineered structures. What is new is the inclusion of a number of other Nano- based approaches to medicinal studies. For example, the antibodyconjugated nanosized liposomes demonstrate significant improvement over conventional, lessdirected drug delivery protocols. Monoclonal antibodies and vaccines directed against tumors have been extensively studied, while antisense oligonucleotides and siRNAs are more recent additions to the nanomedicine repertoire.
Tumor destruction via the use of nanoshells for thermal ablation is also being examined and shows promise as a nonsurgical method for tumor removal. Precise knowledge of the normal and cancer genome is at hand, and the structure and function of all genes are now within grasp of the medicinal chemist and drug developers. This will allow the creation of nontoxic, targeted small-molecule drugs for use in the oncology clinic. Due to the complexity of cancers, a combination of approaches will likely be needed for the effective elimination of all tumor cells.

Therefore, clinical protocols for first-in-human studies with novel treatments frequently specify staggered product dosing and sufficient monitoring after the initial product administration, before subsequent trial participants are dosed with the new therapy. The more that is discovered about how to optimize gene delivery vectors, the closer this field gets to delivering wide-scale solutions to modern medicine. AAV is considered a powerful vector in targeting the liver for treating hematological diseases. As the drug carrier penetrates further into the lung, additional shedding will allow the encapsulated drug to be released. Naturally occurring singleton residues in AAV capsid impact vector performance and illustrate structural constraints.
