Confocal Raman Microscopy of Streptococcus Sanguis and Mutans
Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008Confocal Raman microscopy has been used to differentiate the spectra from biofilms of oral bacterial species Streptococcus sanguis and mutans. Improvements in processing algorithms allow this study to be performed using glass as a substrate.

Raman Instrumentation for Confocal Raman Microscopy
2010Raman spectroscopy is a weak scattering technique in which typically less than one in a million excitation photons give rise to a single Raman photon. The situation is even more difficult in confocal Raman microscopy, as the detection volume is reduced by the small pinhole and thousands of spectra must be collected in a short period of time. Therefore,

[Technique of confocal Raman microscopy on erythrocytes].
Guang pu xue yu guang pu fen xi = Guang pu, 2010The technique of confocal Raman scanning microscopy (point scanning, line scanning and 2D scanning) and bright field imaging of living erythrocytes was investigated as a function of different scanning conditions at the excitation wavelength of 514 nm. The biological effect of the 514 nm laser radiation on the erythrocytes was also evaluated, so that a ...

Imaging theory of nonlinear Raman confocal microscopy
Journal of Modern Optics, 2008A novel nonlinear Raman confocal microscopy utilizing Raman induced Kerr effect spectroscopy (RIKES) is presented in this paper. The imaging theory of RIKES confocal microscopy with Gaussian beam is derived. The imaging properties of RIKES confocal microscopy and the impact of different beam waist widths of Gaussian beam on the lateral and axial ...

Confocal Raman microscopy on single living young and old erythrocytes
Biopolymers, 2008AbstractRaman confocal microscopy, including the techniques of point Raman spectra, line mapping, 2D mapping, and time‐dependent spectrum monitoring performed with 514.5 nm excitation light, was used in a comparative study on the distribution and oxidation states of hemoglobin (Hb) in young and old mature erythrocytes.

Pushing the limit of confocal polarized Raman microscopy
Canadian Journal of Chemistry, 2007Raman microscopy has emerged as a powerful technique to characterize anisotropic materials with sub micro meter resolution. The use of polarized light allows one to obtain precise information about the local organization of the relevant molecular groups through the determination of the most probable distribution function.

Studies of photopolymer heterogeneties by Confocal Raman Microscopy
2012Photopolymers are used in a wide range of industrial applications (graphic arts, microelectronic, coatings...). Oxygen inhibition is most of the time an issue in free radical photopolymerization performed in air. As a result, the structure of the cured polymer coating shows heterogeneities across the depth of the film: a gradient of conversion is ...

Confocal Raman Microscopy to image targeted chemotherapy
2018The Side effects of chemotherapy in cancer treatments are unavoidable due to the lack of anticancer drug’s specificity and it has a painful impact on patient quality of life. Over the past 30 years, increasing efforts is done to optimize chemotherapy dosing to reduce drug toxicity while increasing its efficacy.
