Raman image of a SiC wafer. The images area is approximately 1 mm2, and shows inclusions of 6H-Silicon carbide, 3C-Silicon carbide or Si (red), voids (black). The strain distribution is shown as blue to green. Raman image of montelukast sodium API within an oral tablet. API domains are...
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 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...
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 ...

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. ...
