Peptide Nanomaterials: The Future of Biomaterials and Drug Delivery

3/17/2021 11:50 - 12:25

Peptides represent a promising class of molecules for healthcare applications. Their chemical versatility (i.e. wide availability of functional groups) mean they can be designed, using a bottom up approach, to provide very specific functional and biological properties. Our research has shown very short peptide sequences (<10 amino acids) can be modified/synthesised to form fibrous (hydrogel) and tubular (nanotubes) nanostructures in response to a variety of physiological stimuli (pH change, enzymes). These peptide materials have the potential to be harnessed for future use as: antimicrobial/anti-biofilm agents (hydrogels, nanotubes); medical device coatings (hydrogels); wound healing (hydrogels); drug delivery platforms to cross biological barriers (nanotubes) and injectable in situ forming implants for sustained drug delivery (hydrogels).
