Biomedical Application

Protein in Device

Structural assembly of certain proteins can be used to construct metal-protein conjugates and their two-dimensional network. Our group develops a biohybrid memory where protein-capped particles serve as nanoscale charge traps. The proteins in this device also assume the electrical function of tunnel dielectrics.

Electrolyte-Gated Systems

Field-effect or electrochemical mode electrolyte-gated transistors are studied for their integration into biosensing platforms. We use conducting polymer and oxide semiconductor channels to build ion sensitive electrolyte-gated systems and develop novel approaches to combine their sensing and memory functionalities.

Optical Sensing

Thin-film photon emission and detection components can be arranged to build a versatile healthcare platform such as a pulse oximeter, with a flexible, portable and wearable form factor. We investigate wavelength selective light-emitting diodes, photodiodes and phototransistors for their use in optical sensing technology.
