A white-light source operated polymer-based micromachined Fabry-Perot biochemical sensor is reported. As a refractive-index sensitive optical sensor, its transducing signal varies upon the changes of the effective refractive index in the Fabry-Perot cavity. This sensor is fabricated from PDMS and glass. More specifically, this sensor is a micromachined Fabry-Perot interferometer (microFPI) and is fabricated by bonding a glass substrate and the soft-lithographically patterned PDMS. Several biochemicals have been detected with the microFPI biochemical sensors. Measurements show that rabbit IgG at a concentration of as low as 5 to 50 ng/ml can be detected even without any performance optimization of the devices.
