Abstract

The adaptive property of e-beam evaporated silver films was investigated and employed for protein sensing with surface-enhanced Raman scattering (SERS). The approach for sensing proteins was based on adaptive silver films (ASF). It was demonstrated that adaptive nanostructured films can be used for the observation of differences in SERS spectra of recombinant human insulin and insulin lispro at sub-monolayer protein surface densities and provide macroscopic enhancement factor of about 3×10 6. The stabilization and the restructuring of the ASFs by the proteins was also presented.
