Biodegradable Natural Polymers

Natural polymers have proved to be useful in versatile applications, including controlled drug delivery, gene delivery, regenerative medicine, and other biomedical applications. These polymers are obtained primarily from plants, animals, and microbial sources which are again classified based on their chemistry into polysaccharide, protein, polyester, polyamide-based polymers. The in-depth surveys of these polymers reveals their malleable nature to be modified for various applications. Also, their responsive chemical linkages provide ease of biodegradability, which in turn makes them biocompatible. Their desirable features of ample abundance, biocompatibility, and biodegradability make them potential material for various uses. The eco-friendly profile of these polymers makes researchers inclined towards alluring natural polymers. This chapter describes natural polymers obtained from different sources and provides insights on the origin, chemistry, key features, applications, and marketed products of natural polymers that are being explored as adaptable materials in multifaceted areas.
