Abstract
A surface enhanced luminescence (SEL) sensor may include a substrate and nano fingers projecting from the substrate. The nano fingers may include a nano finger extending along an axis. The nano finger may include a plasmonically active cap and a pillar supporting the plasmonically active cap. The pillar may have an asymmetric material composition with respect to the axis.
Claims15
A surface enhanced luminescence (SEL) sensor comprising:
- a substrate;
- nano fingers projecting from the substrate, the nano fingers comprising a nano finger extending along an axis and comprising:
- a plasmonically active cap;
- and
- a pillar supporting the plasmonically active cap, the pillar having an asymmetric material composition with respect to the axis.
2 more elements
A method comprising:
- providing nano fingers extending from a substrate along respective axes;
- and
- modifying the nano fingers to provide each of the nano fingers with an asymmetric material composition with respect to their respective axes.
A method comprising:
- exposing nano fingers to an analyte, each of the nano fingers extending along a respective axis and having an asymmetric material composition with respect to the respective axis;
- and
- apply stimulus to the nano fingers to actuate bending of tips of the nano fingerse towards one another to capture the analyte between the tips.
