Polymers of natural origin are termed as ‘Biopolymers’. These are abundant in nature and are either derived directly from biological systems or chemically synthesized from biological building blocks. The major reason that biopolymers have gained popularity as carriers for drug delivery is that they offer a plethora of advantages over conventional polymers. Biopolymers are non-toxic and biocompatible, thus making them a versatile carrier. They offer the economic advantage as they are relatively cheap. Biopolymers offer environmental advantages as well because they are biodegradable.
