Abstract
Disclosed herein are aspects of a flexible surface plasmon resonance (SPR) chip and a sensor comprising the chip. The surface of the SPR chip may be further functionalized to provide or enhance selectivity and/or sensitivity to a desired analyte. In some aspects, the chip comprises a polyimide substrate and a plasmonic metal layer on the substrate. The plasmonic metal layer may be further functionalized. Also disclosed are methods for making and using the SPR chip.
Claims20
A flexible surface plasmon resonance sensor, comprising:
- a flexible substrate having a first surface and a second surface;
- and
- a plasmonic metal layer in direct physical contact with the first surface of the flexible substrate, the plasmonic metal layer having a metal layer thickness of from greater than zero to 60 nm;
- wherein the flexible surface plasmon resonance sensor does not comprise an adhesion layer between the substrate and the plasmonic metal layer.
