ABSTRACT
Collagen is the sole most profuse fibrous protein in the animal kingdom, and it was considered as the primary building block of connective tissues and serve as scaffolds for therapeutic agents. The application of collagen was extended both in vivo and in vitro studies as it was considered as a potential biomaterial with excellent biodegradability, biocompatibility, and weak antigenicity. This chapter emphasized collective information of collagen in terms of its structure, properties, and applications. Also, this chapter addresses the compilation of vast information on the biomedical application of collagen in cancer therapy, drug delivery, tissue engineering, and so on. We have discussed in detail the recent papers covering collagen-based biomaterials which were supposed to become the most prominent material in the field of pharmaceutics in the near future.
