Recent exploration of bio-mimetic nanomaterial for potential biomedical applications

Highlights: • The development of bio-inspired functional materials by using discovery, interpreting, and invention. • The discovery, natural materials are copied as the source of inspiration. • The interpreting natural beauty through a logical experimental ways and reverse engineering. • The interpreted knowledge from nature is used to develop different multifunctional healthcare materials. - Abstract: Bio-inspired materials with the multiscale skeleton show intrinsic multifunctional integration. This special biological characteristic is designed and developed to encourage scientists and engineers to multiobjective artificial physicals with multiscale frameworks. This review focuses on some recent development in the areas of classical biomaterials including lotus leaves, butterfly wings, red rose petals, spider silks and the associated multiscale frameworks acquiring function coalescence. We have also addressed some queries and standpoints for bio-inspired form of drug delivery using pathogens, which sheds light on delivery of proteins, small interfering RNA and other therapeutic agents.
