Abstract
A surface enhanced Raman spectroscopy (SERS) sensor may include a nano structured surface and a nonstoichiometric oxide layer. The nano structured surfers may include a first peak, a second peak and a valley between the first peak and the second peak. The non-stoichiometric oxide layer may include a first portion on the first peak and a second portion on the second peak.

A surface enhanced Raman spectroscopy (SERS) sensor comprising:
- a nano structured surface having a first peak, a second peak and a valley between the first peak and the second peak;
- and
- a non-stoichiometric oxide layer having a first portion on the first peak and a second portion on the second peak.
A method for forming a surface enhanced Raman spectroscopy sensor (SERS) sensor, the method comprising:
- providing a nano structured surface having a first peak, a second peak and a valley between the first peak and the second peak;
- and
- forming a non-stoichiometric oxide layer having a first portion on the first peak and a second portion on the second peak.
A surface enhanced Raman spectroscopy sensor (SERS) sensor comprising:
- a substrate;
- a first column rising from the substrate, the first column having a first top surface comprising a nonstoichiometric oxide material;
- a second column rising from the substrate, having a second top surface comprising a nonstoichiometric oxide material, the first column and the second column having a predefined spacing.
