This project involves incorporating the label-free photonic crystal biosensors within microfluidic networks. By having sensors within the microfluidic channels, bulk reagents or interaction between different biomolecules can be detected in real time with significantly less reagent volume consumption. Within the microchannels, the distance that biomolecules have to travel to reach to the sensor surface is cut down. As a result, the detection time required for bioassays can be significantly reduced and kinetic binding rates between biomolecules can be determined with greater accuracy. In addition, the fluid inlet/outlet locations of the sensor-integrated microfluidic chips are compatible with the standard liquid handling system widely used in life science laboratories.
