Research Interests
SMART POLYMER SYSTEMS AS SENSORS AND ACTUATORS
This research area focuses on the synthesis, and engineering of polymer materials to come up with platforms that may be used as sensors and actuators. The properties of these smart polymers are often improved by incorporation of materials in nanostate dimensions. Current specific applications include olfactory and taste sensing, and controlling of drug and fertilizer release.
