Preparation of Chitosan Microparticles by Spray Drying

Microparticles with controlled size and morphology are of significant interest in the fields of drug delivery and biopharmaceuticals. The objective of this study was to assess the effect of processing parameters on the ability to control the size and distribution of chitosan based microparticles, targeting diameter range of 1-10 µm. The effect of encapsulating bovine serum albumin (BSA), a model protein, as well as sodium tripolyphosphate (TPP), a cross-linker, was studied.

Chitosan-based Biomaterials

Chitin, a natural polysaccharide, is the second most abundant natural biopolymer in the world, after cellulose.

Chitosan: A Versatile Platform for Pharmaceutical Applications

The development of new medical devices and pharmaceuticals plays an integral role in the medical industry. Both natural and synthetic polymers possess benefits that make them valuable components in therapeutics.
