Abstract

Label-free biosensors based on polymeric waveguides with Bragg reflection grating are demonstrated for the purpose of the highly sensitive protein detectors. Due to the unique processibility of the polymers in terms of nano-imprinting and the injection molding, the polymer waveguide devices has large potential to provide cost-effective solution for the disposable biosensors as long as robust immunoassay process is developed. The large contrast waveguide consisting of low index fluorinated polymer exhibits enhanced sensitivity of detecting cover index variation by 1.9 times.
