Development of a gel-based SERS biosensor.
Developed and study of gel-based SERS biosensors. Successfully detected bilirubin and cortisol using the gel sensor. Studying the diffusion of biomarkers in the gel.
This work resulted in three publications in Cellulose, Journal of Physical Chemistry C, and Applied Nanoscience. This work was funded by the Center of Innovation (COI) Program, Japan Science and Technology Agency.
-
Development and study of nanocavity sensor.
Developed periodic Ag nanoslits with nano roughness to couple localized surface plasmon resonance (LSP) and surface plasmon polaritons (SPP) to increase SERS signal strength. Demonstrated practical application of SERS substrates by the detection of the bilirubin in trace concentrations.
This work resulted in a publication in ACS Applied Biomaterials. This work was funded by the Center of Innovation (COI) Program, Japan Science and Technology Agency.
