BiopolymersBiopolymers are naturally occurring polymers from living organisms such as bacteria and plants, offering a green and sustainable option compared to traditional petroleum-based polymers. Chain molecules composed of repeating chemical units from renewable sources, being biodegradable and non-toxic, are attracting attention as biopolymers. Biopolymers are exploited to minimize dependence on non-renewable sources and reduce pollution by synthetic materials. They are non-toxic and biodegradable, hence promising candidates for application in a wide range of fields, particularly pharmaceuticals and biomedical sciences. The chapter addresses the elementary characteristics of polymers and biopolymersBiopolymers and their application in biomedical applications such as wound healing, drug delivery, and tissue engineering. For biomedical applications, the material ought to be biocompatible, degradable to non-toxic products, possess low antigenicity, and high bioactivity, induce cell growth and proliferation, and be processable into complex shapes with appropriate porosity and appropriate mechanical behavior. In addition, processability into complex shapes with appropriate porosity and appropriate mechanical behavior are crucial factors. The chapter gives an overview of biodegradable biopolymers and their significance in biomedical applications. The most accessible and prevalent biopolymersBiopolymers are addressed, with emphasis on their characteristics and biomedical innovation potential.
