Detection of chemical analytes by array of surface enhanced Raman scattering reactions

摘要

A device (and methods of using and manufacturing the device) having a substrate; and a plurality of spots comprising surface enhanced Raman scattering (SERS) active particles attached to the substrate, wherein the SERS active particles reflect an incoming Raman signal to produce a reflected Raman signal having a higher intensity than that of the incoming Raman signal are disclosed. Also a device (and methods of using and manufacturing the device) a substrate; and a plurality of spots comprising composite-organic-inorganic-nanoparticles (COINs) attached to the substrate are disclosed.
