Paper Abstract

Surface plasmon resonance sensors are a popular technology for the optical detection of surface adsorption, for applications ranging from drug-development to pathogen detection. Here, we will discuss the integration of nano-hole arrays to provide high-sensitivity detection, with a lower detection limit, speed and cost. Calculations will be presented that suggest that in-hole detection is more sensitive than detecting binding from the surface around the nano-holes. In-hole detection also has the benefit of increased speed due to rapid diffusive transport, yet it provides the challenge of microfluidic/nanofluidic integration. We will outline our recent efforts to produce nano-hole arrays with through-hole detection.
