The spectral signature of the cell component can be obtained through the Raman scattering effect, which occurs when a photon is excited in a low vibrational state, i.e., a higher virtual state (Fig. 2). As there is no electronic state shift, the system cannot exist in the virtual state...
Though the three different types of colloids have comparable surface potential and concentration, citrate-Au colloids exhibit a much lower efficiency than the other two Ag colloids due to a poorer plasmonic effect. Additionally, the efficiency of citrate-Ag colloids is slightly lower than Hya-Ag ...
The combination of both imaging methods enables us to emphasize the role of plasmon coupling and antenna effect in the surface-enhanced Raman scattering enhancement.doi:10.1111/j.1365-2818.2008.01885.xJohn Wiley & Sons, LtdJournal of Microscopy...
These maps were then used to model the effect of using a Raman spectroscopic probe by selecting 5 and 10 probe points across the mapped images and evaluating the impact on disease detection. Results demonstrated sensitivities of up to 81% and specificities of up to 97% when differentiating ...
We analyze the optical resolution of Fourier transform spectral interferometric-coherent anti-Stokes Raman scattering microscopy, which extracts the complex amplitude of an image by using a spectral interferometric effect. Image-formation formulas are presented that describe the properties of the image obser...
In this microprobe configuration, the pump enhancement originates from both high-Q WGMs and nanoscale plasmonics, while the Purcell effect is mostly contributed by the broadband plasmonic resonance. Note that the Raman intensity would be further increased if the emission were also enhanced by WGMs. ...
Using several approaches, including electromagnetically induced transparency (EIT), gradient echo memory (GEM), the off-resonant Faraday effect, and far off-resonant Raman memory, optical memory has been demonstrated in cold atomic ensembles2,7,8,9, atomic vapors10,11,12,13,14, and solids15,16...
