There is a strong need for low-cost, disposable, label-free biosensors to enable fast, on-site biomedical and chemical detection. Among the various biosensors, guided-mode-resonance (GMR) biosensors have attracted increasing attention for practical biomedical and chemical applications because of the advantages of their simple structure, simple fabrication, and high sensitivity. However, there exist challenges to fabricate sub-wavelength periodic patterns for successful GMR biosensors in a cost-efficient way. In our previous works, we have employed injection-molded technique to fabricate GMR biosensors, and demonstrated sensitivity of up to 181.9 nm/RIU. In this paper, we report on a study of polarization-dependent optical responses for the injection-molded GMR (IM-GMR) biosensors.
