Exploring the Role of Natural, Synthetic, and Biodegradable Polymers in Biomedical Applications

Biomedical applications rely on polymers because these materials possess adjustable properties (chemical/physical). This chapter evaluates healing function of natural & synthetic polymers within wound healing applications & drug delivery systems alongside their implementation in tissue engineering & regenerative medicine. Biocompatibility along with degradability in nature found within polymers (collagen, chitosan & alginate) make them fit for use as scaffolds alongside drug carriers. Synthetic polymers (polylactic acid & polycaprolactone) deliver adjustable mechanical stability benefits which make them valuable for implants with drug delivery applications. Processing technologies have been improved through 3D printing & electrospinning to develop medical structures which match individual healthcare requirements precisely. Use of polymers for biomedical applications still faces ongoing issues pertaining to biocompatibility as well as scalability and regulatory compliance requirements. Solving these challenges will enable polymer-based materials to succeed in clinical applications
