Abstract:
1. A surface-enhanced Raman spectroscopic (SERS) system, comprising: an array of nanorods on a surface of a substrate, wherein a tilt angle β between an individual nanorod and the substrate surface is less than 90°; one or more first biomolecules disposed on one or more of the nanorods, wherein the array of nanorods in combination with the first biomolecule has a first measurable surface-enhanced Raman spectroscopic signature, wherein the first biomolecule has an affinity for a second biomolecule, wherein the array of nanorods in combination with the first biomolecule and the second biomolecule has a second measurable surface-enhanced Raman spectroscopic signature that is different than the first measurable surface-enhanced Raman spectroscopic signature.
