Research Summary

Dr. Andrew Lyon’s research interests center around the development and implementation of new environmentally responsive (or “smart”) materials for photonic materials, bioanalysis, and biomimetics. The approach the group is taking is to design hydrogel nanoparticles that undergo large changes in their chemical, mechanical, optical, or electrical makeup in response to a chemical stumulus, biomolecular interaction, or electromagnetic field; such materials can be viewed as amplifiers or sensitizers of the environmental event. As a result of their environmental sensitivity, nanogels have potential in a number of applications. For example, nanogels have recently been assembled into a new type of soft-sphere photonic crystal that displays advantageous optical and mechanical properties over hard-sphere analogues. Other application targets for responsive hydrogels include biosensors, artificial muscles, drug delivery systems, and chemical separations. Specific projects currently underway in the Lyon group include studies of hydrogel nanoparticle bioconjugates, core-shell hydrogel nanoparticles, processable photonic crystals, polymeric microlenses, thin films for drug delivery, tunable colloidal crystal optical filters, and fast-responding nanostructured polymer films.
