Drugs, nanoscale particle preparation

Nanoparticles are solid species of nanoscale size usually composed of an insoluble and biodegradable polymer or polymer blend (Figure 47. IB). Generally, the methods of preparation of such nanoparticles are simple and easy to scale-up. The drug is captured within the particle upon its preparation and is released upon degradation of the polymer in the body. The use of nanoparticles as carriers for drug and gene delivery has been...
