Classification: CPC G | IPC G

Claim 0:
1. An analyte detection system, comprising:
(a) a flow cell comprising an analyte sensor, wherein the analyte sensor comprises:
(i) a transparent substrate; and
(ii) an analyte-sensitive film on a surface region of the substrate, wherein the analyte-sensitive film comprises a plurality of metallic nanoparticles having an affinity for the analyte;

(b) a light source configured for directing light along a first path extending through the transparent substrate to the analyte-sensitive film;
(c) a light detector configured for detecting a localized surface plasmon resonance (LSPR) signal from the analyte-sensitive film; and
(d) a temperature-control unit for maintaining the analyte-sensitive film at a substantially constant selected temperature;
wherein the system determines whether the analyte is present in a sample based on a LSPR signal detected from the analyte-sensitive film.
