Abstract

Nanoparticle research is a vibrant area of interest due to its unique functionality and composition. It finds its application in wide variety of fields including biomedical, food processing and drug delivery systems. Polymers are used as a widespread medium for carriers of bioactive components. Biopolymers play a major role because of its biodegradable and biocompatible nature. These biopolymers-based nanoparticles have certain limitations because of their restricted behavior in different solvents. In order to fine-tune these nanoparticles and to make them fit into different real-time applications, surface modification becomes essential. Some of the approaches applicable to modify the polymeric surfaces of these nanoparticles are physical immobilization, adsorption coating or grafting, chemical modifications on the functional groups such as acrylation, amination and acetylation, radiation-induced grafting, UV-ray treatment and plasma surface modification. Such surface modifications on the functional groups provide improved stability and enhanced surface activity of polymeric nanoparticles which are helpful in reducing agglomeration, preventing oxidation and protecting labile compounds. Consequences of which enables specific targeting of active compounds to the site of action. In this view, the chapter explains about the various surface modifications and its applications in food preservation, packaging and controlled release of bioactives.
