ABSTRACT
This chapter focuses on the general concept and biomedical applications of these composites. A composite material is constituted of two or more components. These constituents bear different chemical, physical, or biological properties. Biocomposites and nanocomposites form the most important class of polymer-based composites because of their unique attributes. A myriad of biomaterials such as cellulose, starch, gelatin, fibrin, chitosan, chitin, and collagen are employed to generate composites, hydrogels, and films, which possess enhanced properties. In the field of medicine, protein- and lipid-based composites play an important role in tissue engineering, cancer therapy, drug delivery, anti-infection, wound healing, skin, and dental protection. Biocomposites have a wide range of applications in almost all major fields, ranging from industrial to medical sphere, and have revolutionized textile, cosmetic, automobile, paper, and medicinal industries. Biocomposites have tremendous potential in industrial, textile, agriculture, and medicinal fields. Besides, protein and lipid biocomposites have left a landmark impact in the medical field.
