Outline of Final Research Achievements

We developed a label-free multi-modal biosensor using a MEMS Fabry-Perot interferometer integrated with a CMOS image sensor, which can measure intermolecular force of adsorbed molecules as well as structural change of protein. As a result, we demonstrated 22 times higher stress sensitivity and 100 times higher mass sensitivity than that of conventional biosensors.
