Nanocapsules: An Emerging Drug Delivery System.

Background: Controlled drug release and site-specific delivery of drugs make nanocapsules the most approbative drug delivery system for various kinds of drugs, bioactive, protein, and peptide compounds. Nanocapsules (NCs) are spherical shape microscopic shells consisting of a core (solid or liquid) in which the drug is positioned in a cavity enclosed by a distinctive polymeric membrane.

Objectives: The main objective of the present patent study is to elaborate on various formulation techniques and methods of nanocapsules (NCs).
