Spectral and angular detection of low molecular-weight biomolecules (biotin): (a) reflectance spectra of the sensor at 30° angle of incidence for different concentrations of biotin in PBS, (b) the variation of wavelength shift with different concentrations of biotin, (c) reflectance spectra of the sensor device at 1250 nm for different concentrations of biotin in PBS, and (d) the variation of angular shift with different concentrations of biotin.
