Abstract
A surface enhanced Raman scatter (SERS) analyte analyzer. The analyzer has floating surfaces for enhancement of the Raman scattered light from sample molecules. An injector may provide a spray of charged nanoparticles suspended in droplets of an evaporable solution into a chamber. When the solution quickly evaporates, droplets of nanoparticles are left without a supporting solution. These droplets or cloud of charged nanoparticles may then explode into a dispersion or aerosol. The charged nanoparticles may attract molecules of a sample for attachment to their surfaces. A laser light may impinge the attached molecules which may result in surface enhanced Raman scattered light received by a detector or a light spectrometer. Wavelength signatures may then be obtained from the spectrometer. The signatures may provide information about the molecules.
