Research Interest
Our research focuses on design and development of new biofunctional nanomaterials based on sugar-peptide conjugates. Molecular self-assembly approach will be followed for bottom-up nanofabrication of these soft namomaterials to generate a variety of nanostructures. These supramolecular nanomaterial scaffolds will be explored towards solving the problems of biology (e.g. drug delivery, cancer therapy, regenerative medicine) and energy resources.
