Paper Abstract

Nanoscale electric field confinement and enhancement is a well known phenomenon for small particles and flat interfaces. Senspex is using E-Beam lithography to develop nanosensors for the detection of biological and chemical hazards. The sensors that are being developed are a square array of metallic cubes; each cube has dimensions of approximately 100nm x 100nm x 30nm and a pitch of 125nm in the x- and y-directions. Senspex's numerical simulations show that the intense electric field in the minute volume between the cubes will lead to a high probability of detection for small concentrations of analyte in real world situations.
