Abstract
A plasmonic analyte interrogation stage may include a plasmonically active surface and a transition metal photocatalytic layer on the plasmonically active surface.
Claims15
A plasmonic analyte interrogation stage comprising:
- a plasmonically active surface;
- and
- a transition metal photocatalytic layer on the plasmonically active surface.
A surface enhanced luminescence (SEL) sensing stage comprising:
- a substrate;
- pillars rising from the substrate;
- each pillar comprising:
- a rod formed from a non-photocatalytic material;
- a plasmonically active cap supported by the rod;
- and
- a transition metal photocatalytic layer proximate the plasmonically active cap.
4 more elements
A method comprising:
- irradiating a transition metal photocatalytic layer upon an analyte free plasmonically active surface to clean contaminants from the analyte free plasmonically active surface;
- binding an analyte on or approximate to the cleaned plasmonically active surface;
- and
- irradiating the analyte and the plasmonically active surface to interrogate the analyte.
