Abstract

Results will be reported from efforts to develop a self-contained micromachined microfluidic detection system for the presence of specific target analytes under the US Office of Naval Research CIED Basic Research Program. Our efforts emphasize improving/optimizing a dedicated micromachined sensor array with integrated photodetectors that are coupled to chemically sensitized chemiluminescent receptors. Here we will review our work on the fabrication of integrated photodiodes within an array of micromachined silicon pyramidal cavities that will contain the chemiluminescent compounds. One particular advantage of such approach over a conventional planar photodiode would be its collection efficiency without the use of external optical components. This should allow a more compact and robust system to be constructed by integrating photodetection and fluidics into a single chip-based platform. Additionally, overview of accessing the photodiode using wireless coupling to a resonant chemically sensitive tag will be discussed.
