Emulated transmission in confocal Raman microscopy
Journal of the Optical Society of America B: Optical Physics, 2007We propose to use a mirror to simulate transmission configuration in a reflection confocal optical and Raman microscopy. Such a configuration allows an increased contrast of optical images of cells and increases the efficiency of Raman signal detection from cells by a factor of two.

Insight into pollutant bioavailability and toxicity using Raman confocal microscopy
Journal of Microbiological Methods, 2005Raman confocal microscopy was used to discriminate between cultures of Burkholderia xenovorans LB400 exposed to four different common environmental pollutants: phenanthrene, dodecane, 3-chlorobiphenyl and pentachlorophenol. Evidence is presented for the application of Raman spectroscopy as a bioassay for pollutant bioavailability and toxicity.

Characterization of a hazardous eyeliner (kohl) by confocal Raman microscopy
Journal of Hazardous Materials, 2005A new method of analyzing kohl, a cosmetic eyeliner, using confocal Raman microscopy is reported. This technique offers an important alternative to conventional spectroscopic techniques that provide elemental/atomic composition. Raman spectra of three kohl samples have been measured between 150 and 3000 cm(-1) at room temperature. The main component of

Confocal Raman microscopy of supercritical fluid dyeing of polymers
The Analyst, 2003Supercritical CO2 was used as a medium to introduce azo-dyes into polymers (PMMA and PET). Confocal Raman microscopy has been applied using dry metallurgical and oil objectives to measure the concentration of dye as a function of distance from the surface to the core of the polymer samples.

Confocal Raman Microscopy of Optical-Trapped Particles in Liquids
Annual Review of Analytical Chemistry, 2010The in situ analysis of small, dispersed particles in liquids is a challenging problem, the successful solution to which influences diverse applications of colloidal particles in materials science, synthetic chemistry, and molecular biology. Optical trapping of small particles with a tightly focused laser beam can be combined with confocal Raman ...

Confocal Raman Microscopy of Protein Adsorbed in Chromatographic Particles
Analytical Chemistry, 2012Confocal Raman microscopy is a nondestructive analytical technique that combines the chemical information from vibrational spectroscopy with the spatial resolution of confocal microscopy. It was applied, for the first time, to measure conformation and distribution of protein adsorbed in wetted chromatographic particles.

Characterization of Ionomer Membranes with Confocal Raman Microscopy
ECS Meeting Abstracts, 2020Ionomer membranes are crucial components of electrochemical energy systems such as fuel cells, electrolyzers, or redox-flow batteries. They need to meet demanding requirements for high-performance and long-term stable devices, and a targeted optimization of the membranes requires exact knowledge of parameters such as membrane thickness, ion exchange
