Biomedical exploitation of self assembled peptide based nanostructures.

Nowadays, peptide based disease prevention is an important topic in biomedical science, which may radically change the traditional use of biomaterials and improve the life quality. Self-assembled nanostructured peptides have been receiving extreme attention in the drug delivery field due their high biocompatibility levels, better loading capacity, extended circulation and localization in required target site. This article focuses on the composition and synthesis of different forms of self-assembled peptide nanostructures as nanotubes, nanofibers, nanoparticles, nanotapes and nanogels. The most important properties for their self assembled mechanism and their biomedical applications are also discussed. Various potential applications of nanostructures peptide could be developed designed for therapeutic agent's delivery, biosensors, anticancerous and antimicrobial activities.
