A microscale biosensor for use in the detection of target biological substances including molecules and cells is a microfluidic system with integrated electronics, inlet-outlet ports and interface schemes, high sensitivity detection of pathogen specificity, and processing of biological materials at semiconductor interfaces. A fabrication process includes an all top-side processing for the formation of fluidic channels, planar fluidic interface ports, integrated metal electrodes for impedance measurements, and a glass cover sealing the non-planar topography of the chip using spin-on-glass as an intermediate bonding layer. Detection sensitivity is enhanced by small fluid volumes, use of a low-conductivity buffer, and electrical magnitude or phase measurements over a range of frequencies.
