Tunable, Liquid Resistant Tip Enhanced Raman Spectroscopy Probes: Toward Label-Free Nano-Resolved Imaging of Biological Systems.Tip enhanced Raman spectroscopy (TERS) has been established as a powerful, noninvasive technique for chemical identification at the nanoscale.  Here TERS probes for studies in aqueous environments have been demonstrated using titanium nitride coatings with an alumina protective layer.
