Paper Abstract

With the development of a point of care (POC) biosensor in mind, a polymer-molding prism with double parabolic surfaces is invented and developed to implement an ultra-compact SPR biosensor with extremely high sensitivity. The polymer molded parabolic prism is cost effective and disposable, thus cross contamination between biological samples can be avoided. A highly sensitive biosensor with a form factor less than 15cm*15cm*5cm was received with a tunable excitation angle of light beam for a large dynamic range. A highly sensitive optical phase interrogation was demonstrated. The biosensor is also compatible to a modern microscopy platform.
