Abstract:
1. An integrated SERS sensor system for the detection of targets including biotargets, said system comprising: at least one sampling platform, said sampling platform having a plurality of mnicrostructured or nanostructured metal surfaces thereon; a plurality of receptor probes disposed on said sampling platform within a range of an enhanced local field emanating from said microstructured metal or nanostructured surfaces upon irradiation, said receptor probes adapted for binding with at least one target molecule, said receptor probes generating a SERS signal when combined with said target molecule responsive to electromagnetic radiation applied thereto at least one excitation source of electromagnetic radiation for producing an optical beam and structure for producing a plurality of optical beams from said optical beam, said plurality of optical beams irradiating for irradiating said plurality of receptor probes, and an integrated circuit-based detection chip optically aligned with said plurality of receptors, said detection system for detection of said SERS signal, wherein said detector chip comprises a plurality of separate detection channels, at least one of said plurality of detection channels being dedicated to each of said plurality of receptor probes, and at least one of an integrated signal amplification system and an integrated signal processing system disposed on said chip for each of said plurality of detection channels.
