Sensitive Raman spectroscopy of lipids based on drop deposition using DCDR and SERS
Original language description
Raman spectroscopy is widely used for study of lipids and membrane models. A severe limitation of this technique lies in the low Raman cross section requiring high sample concentrations. We report sensitive detection of synthetic 1,2-dimyristoyl-3-trimethylammonium-propane (DMTAP) lipid employing two Raman techniques with improved sensitivity: drop coating deposition Raman (DCDR) and surface-enhanced Raman scattering (SERS) spectroscopies. DCDR provided well-reproducible DMTAP spectra without considerable loss of its solution properties if measured from the coffee ring' pattern of a drop dried on a SpectRIM(TM) plate. DMTAP was detected at similar to 10 M initial solution concentration, which is about three orders of magnitude lower than that for conventional Raman spectroscopy. Moreover, SERS spectra from dried ring of Ag hydrosol/DMTAP system were obtained down to similar to 0.3 M DMTAP concentration, which means that sensitivity of SERS is about five orders of magnitude higher than
