1. An apparatus, comprising:
a housing;
a fluid channel formed on the housing, wherein the fluid channel is coupled to an inlet and to an outlet; and
a substrate positioned inside the fluid channel, wherein the substrate comprises:
a plasmonic nanostructure; and
a conformal passivation coating deposited at least over the plasmonic nanostructure and formed from a material that protects the plasmonic nanostructure from contamination by ambient conditions and by outgassing products from other components of the substrate, wherein the material is removable from the plasmonic nanostructure using a liquid reagent, wherein the material comprises zinc oxide and a combination of cations.
