METHODS AND DEVICES FOR DETECTION OF ANALYTES USING BLOCH SURFACE WAVE-ENHANCED DIFFRACTION-BASED SENSORS

摘要

The invention features methods and diffraction-based devices for the detection of specific analytes. The devices of the invention contain a periodic dielectric multilayer, which allows for the propagation of Bloch surface waves (BSWs) at the surface of the multilayer, thereby increasing the sensitivity of the device.
