Nanospheres Chitosan as a Targeted Drug Delivery System

<p>Biodegradable nanospheres carriers, have important potential applications for administration of therapeutic molecules. Chitosan (CS) based nanospheres have attracted a lot of attention upon their biological properties such as biodegradability, biocompatibility, bioadhesivity and can reduce systemic side effects and allow for more efficient use of the drug. chitosan is a natural polymer obtained by deacetylation of chitin. After cellulose chitin is the second most abundant polysaccharide in nature. In the present study deals with the formulation and evaluation of surfactant coated and uncoated chitosan nanospheres and its various uses.<br><strong>Keywords</strong>: Chitosan , formulation and evaluation , nanospheres
