Biopolymers are naturally occurring materials formed during the life cycles of green plants, animals, bacteria and fungi. Biopolymers include animal protein- based biopolymers such as wool, silk, gelatin and collagen and polysaccharides such as cellulose, starch, carbohydrate polymers produced by bacteria and fungi. The common protein based biopolymers include albumin, gelatin, legumin, which are commonly used for the preparation of nano structured molecules for drug delivery owing to its benefits like minimal size, nontoxicity, long term stability, and biodegradability. The biopolymer block's unique properties in terms of biodegradability, bioactivity, and biocompatibility enable it to be targeted toward fields of application, such as pharmaceutical science, where self-assembly (for example, micellar aggregates, microgels, polymersomes) is utilized to develop drug delivery systems.
