An essential design of this platform is the use of gold nanoparticles or nanorods codecorated with specially reduced antibody half-fragments, nonfluorescent Raman-active dyes, and passivating proteins as the SERS nanoparticles. These nanoparticles offer a facile approach to accomplish orientation...
To amplify the signal, our group has recently developed a simple strategy to prepare ultra-bright Raman dots (Rdots) by non-covalently doping polymer nanoparticles with Raman-active dyes32. When coupled with stimulated Raman scattering (SRS) microscopy, these Rdots show a superb imaging ...
Multiplexed detection of oligonucleotide targets has been performed with gold nanoparticle probes labeled with oligonucleotides and Raman-active dyes. The gold nanoparticles facilitate the formation of a silver coating that acts as a surface-enhanced Raman scattering promoter for the dye-labeled particles ...
Like GC-MS and LC-MS,Raman spectroscopycan serve as a confirmatory testing method[1]. Raman measurements are not affected by the presence of water due to the fact that water is not Raman active; considering that biological specimens typically have high water contents, this technique is extremely...

Hand sanitizers contain up to a dozen inactive ingredients, such as carbomer, triethanolamine, propylene glycol, tocopherol acetate, dyes, and scents. The resulting spectrum is more complicated than ethanol in water, but the 880-cm-1 peak remains very clear (Figure 2). Though most brand-name ...

Result and Discussion Broadband Stimulated Raman spectroscopy exploits the macroscopic nonlinear third order polarization (P(3)) induced in a Raman-active medium by the spatial and temporal overlap of a narrowband RP and femtosecond PP pulses, to obtain high quality Raman spectra. The nonl...
