Advancements in nanotechnology for drug delivery

The practice of nano-technology to deliver drugs has materialized as a viable pathway to overcome obstacles posed by traditional drug delivery. Nanomaterials have unusual physiochemical properties that allow for enhanced drug bioavailability, targeted drug delivery, and increased therapeutic effectiveness. The discussion in this chapter includes: general considerations in nanotechnology and drug delivery, a discussion of nanoparticles as drug-carriers and the practice of nanocarriers in drug-delivery. Applications of nanocarrier drug delivery techniques are illustrated concerning the treatment of cancer, gene therapy, immunotherapy and communicable disease therapy.
