We have developed a number of novel technology to fabricate nanostructures and apply them to sensor and transducer devices. We aim at developing facile, low-cost and high-throughput fabrication processes for high-performance and reliable devices. Specifically, we develop wet-chemical processes, screen printing and inkjet printing methods for synthesis, integration and patterning nanomaterials.

We have developed environmental sensors by using unique physical and chemical properties of nanomaterials and high surface-to-volume ratio of nanostructures. These nanomaterial based gas sensors detect extremely low concentration of gases, and their array devices measure concentration of target gases in gas mixtures.

We have developed bio sensors based on optical and electrochemical methods. The sophisticatedly designed nanostructures concentrate the electric field and that contributes to detecting extremely low concentration of molecules by using surface-enhanced Raman spectroscopy (SERS).
