Raman spectrometer in a confocal microscope mode of operation. This was accomplished without optimization of silver colloidal soln. Incorporation of the colloidal solns. However, SERS spectra degrade if the capillary is not rinsed between expts. In the case of the latter solute, the injected quantity was approx.
