Research Interests
Our research efforts are focused on the area of optical and
electrochemical sensors based on highly selective ion carriers. We are
exploring the applications of the ion-selective sensors relevant to
medicine, biology, and environmental analysis.
Current research projects include:
- External photochemical control of ion-selective optical
sensors via photoactivated compounds.
- Application of nonequilibrium electrochemical methods to
the ion-selective electrodes.
