This document discusses the application of nanocarriers in the delivery of biotechnologicals. It defines nanocarriers as colloidal particulate systems between 10-1000nm that have been used for diagnosis, treatment, and monitoring of diseases. The document then classifies and describes various types of nanocarriers - nanocapsules, nanoparticles, nanoemulsions, nanosomes, dendrimers, nanotubes, and nanosuspensions. It provides examples of each type and discusses their applications in areas like cancer treatment, food/nutraceutical usage, and drug delivery through oral, parenteral, and other routes. The document concludes by listing references used for more information on pharmaceutical applications of these nanoparticulate
