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 ...
First experimental evidence that the SERS enhancement factor effect can be observed on Ag and Au colloids (nanoparticles). Article CAS Google Scholar Stöckle, R. M., Suh, Y. D., Deckert, V. & Zenobi, R. Nanoscale chemical analysis by tip-enhanced Raman spectroscopy. Chem. Phys. Lett...
Since Raman microscopy uses light鈥搈aterial interactions associated with vibrational excitation of molecules, the spatial resolution of the microscope is limited to the half of the wavelength used to induce the Raman effect. In this chapter, we introduce various attempts for breaking the limit of ...
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...
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...
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. ...
The effect of these parameters on the overall morphology of these deposits is shown to be promising as a new technique for the engineering of sub-micron nanoparticle structures. Ag films with laser-induced sub-micron periodic structures were evaluated as substrates for surface-enhanced Raman ...
for the longer time of exposure the apoptotic properties of TNF-α might have essential impact on cell viability and could dominate over pro-inflammatory effect36. The increase of the overall size of the surface covered with lipid bodies caused by formation of droplets of unsaturated character is...
