Optical Properties

We can tune the absorbance and scattering of materials throughout the visible and infrared spectrum by changing the morphology and composition of the nanomaterials. Additionally, we can incorporate fluorophores for light emission at desired wavelengths or attach reporter molecules to give strong Raman signals.
