Surface Enhanced Raman Spectroscopy of Lactoferrin Adsorbed on Silvered Porous Silicon Covered with Graphene.

We registered surface enhanced Raman scattering (SERS) spectra of the human lactoferrin molecules adsorbed on a silvered porous silicon (<i>por</i>-Si) from 10^-6⁻10^-18 M solutions. It was found that the <i>por</i>-Si template causes a negative surface potential of silver partic... View More
