They used the principle that the specific binding of antigens and antibodies causes the bandgap shift of photonic crystals, and realized label-free quantitative detection of porcine immunoglobulins by analyzing the movement of the bandgap of photonic crystals. In 2014, Long et al. used a halogen lamp as the light source, a collimating lens group and a commercial diffraction grating, combined with a smartphone camera, to build a spectral analysis device that can be used for ELISA reactions.
