The laboratory was closed due to retirement; but I have continued to carry out research projects at KAKENHI (Grants-in-Aid for Scientific Research) from 2023.

Our research includes the development of biodevices (photodetector with the visual function, position sensitive detector, and image filter mimicking receptive field) applying photosynthetic protein that resembles visual pigments. Using an inkjet printer, we also apply the protein and conductive polymers to photovoltaic elements.
