Effects of specific binding between anti-human IgG and human IgG. (a) With 10− 3 g/ml human IgG coated on the silica wall, WGM wavelength shift responses when LCs are exposed to various proteins (BSA, anti-HSA, anti-mouse IgG and anti-human IgG) at the same concentration of 10− 3 g/ml. (b) WGM spectral shift resulted from antibody-antigen binding events between 10− 3 g/ml Human IgG and different concentrations of goat anti-human IgG
