Drug Delivery, Nanomedicine, Sensors
We are developing pH, light, or temperature-responsive "smart" gels, capsules, and self-assemblies for the controlled and triggered delivery of drugs, proteins, or cosmetics. Nanoparticles are being developed for use in MRI-imaging of cancer tumors. Thermogelling or photogelling "smart" fluids are under investigation for use in fire-fighting and in microfluidic sensors and valves. Superabsorbent hydrogels are being employed as temperature sensors. Vesicle-coated polymers are being studied as "smart" surfaces for biological assays.
