Abstract
The development of nanoparticle-based drug formulations has yielded the opportunities to deal with and treat diseases. Nanoparticles in drug delivery vary in size but are generally ranging from 10 to 100 nm. Through the manipulation of size, surface characteristics and material used, the nanoparticles will be developed into smart systems, encasing therapeutic and imaging agents in addition to bearing stealth property. Further, these systems can deliver drug to specific tissues and provide controlled release therapy. However, for these novel delivery methods to succeed and compete with those already on the market, the prime issues that require consideration include device design and safety, efficacy, ease of handling and costeffectiveness. Nanotechnology has proven beneficial in the treatment of cancer and many other diseases, also providing advancement in diagnostic testing. Drug delivery systems have an important role to play in the administration of drugs, vaccines and diagnostic agents. This review provides a detail of the next generation of active constituent delivery technologies.
