Technological advances achieved by biocompatible systems in several areas
have attracted increasing interest in the development of nanometric systems based on
biopolymers. In this context, this chapter describes the use of chitosan biopolymer as a
carrier and base matrix for the development of nanoparticles and nanocapsules.
Chitosan is an abundant natural biopolymer in nature, which is renewable,
biocompatible, has hemostatic and mucoadhesive characteristics, and is an interesting
polymer material in the development of nanometric systems. Most of the preparation
methods are based on green routes without the presence of organic solvents and toxic
agents. Chitosan based nanoparticulated systems can be easily reproduced through
simple and easy routes, and applied in various fields such as: food and nutrition
industry, agricultural, pharmaceutical, medical, renewable materials, controlled
delivery, nanoencapsulation, environmental remediation, adsorption, among others.
