Multi-functional biochip for biological agent detection

Multifunctional biochip (MFB) is a unique system that allows simultaneous detection of multiple biotargets simultaneously. The MFB is an integrated multi-array biochip, which is designed by combining integrated circuit elements, an electro-optics excitation/detection system, and bioreceptor probes into a self-contained and integrated microdevice. The multi-functional capability of MFB is demonstrated using the biochip as both an antibody-based and DNA sensor. The study indicates that the biochip technology provides an important tool to warn of exposure to pathogenic agents for use in human health protection and homeland defense.
