sample clean-uppathogentissuemicrofluidicsoptical tweezersRaman spectroscopy and its variants allow for the investigation of a wide range of biological and biomedical samples, i. e. tissue sections, single cells and small molecules. The obtained information is on a molecular level. By making use of ...
Precision engineered Raman spectrometers for fast and accurate chemical analysis. Raman spectroscopy is used to chemically analyse solids, liquids and gases and is an invaluable tool for material identification and verification. Renishaw design and manuf
spectroscopy (including the sensitivity to small structural changes, non-invasive sampling capability, minimal sample preparation, and high spatial resolution) yields a methodology that can provide highly specific molecular information on the microscopic scale. It is this unique combination of sensitivity ...

Raman spectroscopy for quantitative analysis of pharmaceutical solidsdoi:10.1211/jpp.59.2.0005Raman spectroscopy is experiencing a surge in interest in solid-state pharmaceutical applications. It is rapid, non-destructive, no sample preparation is required and measurements can be made in aqueous ...
Raman spectroscopy, (minimal or no sample preparation, non-destructive analysis and speed), suggest that it may also find value for this important application. The Raman spectra of acetaminophen and p-aminophenol are unique (Figure 5A), and spectral analysis of prepared mixtures, as per...
Laser Raman spectroscopy is used to assess the thermal maturity of organic matter in sedimentary rocks, particularly organic-rich mudstones. However, discrepancies exist between quantified Raman spectral parameters and maturity values obtained by vitrinite reflectance. This has prevented the adoption of a ...
As Raman scattering is intrinsic to most biomolecules and is not affected by the presence of water, very little sample preparation is required when carrying out spontaneous Raman spectroscopy.20A wide variety of specimens can be investigated; these include whole organs, tissue sections, cell culture ...
The resonance Raman spectroscopy is a particular application of the general Raman spectroscopy where the incident laser radiation has a frequency that matches the energy of an electronic transition in the sample. From: Practical Approaches to Biological Inorganic Chemistry, 2013 ...
2.20.5.2 Sample Preparation for SERS (Surface Enhanced Raman Spectroscopy) Raman scattering is inherently a weak process where approximately 1% of the photons undergo scattering. The intensity of the scattered light can be magnified by adsorbing the target molecule onto a roughened nanostructured metal ...
