The Hammond research group focuses on the self-assembly of polymeric nanomaterials, with a major emphasis on the use of electrostatics and other complementary interactions to generate functional materials with highly controlled architecture. The uniting theme of the lab - the understanding and use of secondary interactions to guide materials assembly at surfaces and in solution - encompasses three major areas of research:
1) Layer-by-layer controlled release thin film coatings for biomedical implants that address bone regeneration, wound healing, tissue engineering and transdermal delivery from microneedle platforms, 2) Nanoparticle drug carriers for targeted nanoparticle drug, gene, and siRNA delivery for cancer treatment using unique platforms that enable combination and sequenced delivery strategies; and 3) Self-assembled materials systems for electrochemical energy devices, including photovoltaics, fuel cells, and batteries. These polymeric and hybrid materials range from nanoscale electrostatic layered thin film structures with highly controlled function to self-assembled colloids that present nanoscale structure on their surfaces to target cancer cells. Polymer synthetic approaches enable the specialized design of new polymeric systems that can be used in these areas by taking advantage of controlled structure and properties.
