Paper Abstract

Surface plasmon resonance (SPR) biosensing promises a sensitive technique for the rapid quantization of a variety of analytes of interest to environmental sensing, chem/biological warfare detection, and medical screening. For many applications a compact, handheld sensor would be advantageous, however present implementations are not well suited to miniaturization. Using a substrate mode waveguide to excite SPR, a miniaturized SPR system has been demonstrated that is small enough to fit in the palm of a users hand. Preliminary testing has demonstrated 7 nanomolar sensitivity for an immunoassay biosensor.
