Abstract
Novel, cost-effective and label-free Bloch surface plasmon biosensors are presented in this work. The biosensor chip consists of Au waveguides on a truncated 1D photonic crystal supporting Bloch long range surface plasmons (LRSPs) to form an optical biosensor. Gratings capable of coupling perpendicularly incident Gaussian beams are employed as the input-output means. The waveguides are covered with a low index fluoropolymer, etched to form the microfluidic channels and wafer bonded to seal and enable side fluidic interfaces. The devices are fabricated using wafer-scale processes and are capable of multichannel multimodal biosensing. Similar sensitivities to LRSPPs in the corresponding fluoropolymer/solution system are expected with Bloch LRSPPs.
