Description
Performances of surface biosensors are often controlled by the analyte delivery rate to the sensing surface instead of sensors intrinsic detection capabilities. In a microfluidic channel, analyte transports diffusively to the biosensor surface severely limiting its performance. At low concentrations, this limitation, commonly known as mass transport problem, causes impractically long detection times extending from days to months. In this proceeding, we propose and demonstrate a hybrid biosensing platform merging nanoplasmonics and nanofluidics. Unlike conventional approaches where the analytes simply stream pass over the sensing surface, our platform enables targeted delivery of analytes to the sensing surface. Our detection platform is based on extraordinary light transmission effect (EOT) in suspended plasmonic nanohole arrays. The subwavelength size nanoholes here act as nanofluidic channels connecting …
