Abstract

When human tear film’s constituents are identified, it is diagnostically useful. Surface enhanced Raman scattering (SERS) can quickly measure the components at their low concentrations. Reproducible spectra were collected from gold thin film and silver mirror reaction glass substrates. Synthetic tears were measured on optimised substrates as proof of principle. Further statistical analysis is needed to discriminate between diseased and normal tears.
