A new compact surface plasmon resonance (SPR) sensor is presented. The integrated design employs two surface relief gratings imprinted in an injection-molded polymer chip. These gratings replace the traditional glass components usually found in existing SPR sensor systems and offer a low-cost, compact, and robust SPR system with high performance.
