In this work, 26 proteins of different structure, function and properties are investigated by
Raman spectroscopy with 488, 532 and 1064 nm laser lines. The excitation lines were …

Blood is a bodily fluid that is vital for a number of life functions in animals. To a first
approximation, blood is a mildly alkaline aqueous fluid (plasma) in which a large number of …

Raman spectroscopy is an important and powerful technique for analyzing the chemical
composition of biological or nonbiological samples in many fields. A serious challenge …

This Account discusses surface-enhanced Raman scattering at extremely high
enhancement levels that can occur for molecules attached to silver and gold nanoclusters …

We report on the development and testing of a compact laser tweezers Raman spectroscopy
(LTRS) system. The system combines optical trapping and near-infrared Raman …

Nonresonant confocal Raman imaging has been used to map the DNA and the protein
distributions in individual single human cells. The images are obtained on an improved …

SERS spectra of whole human blood, blood plasma, and red blood cells on Au nanoparticle
SiO2 substrates excited at 785 nm have been observed. For the sample preparation …

Resonance Raman spectra of oxygenated and deoxygenated functional erythrocytes
recorded using 785 nm laser excitation are presented. The high-quality spectra show a …

Atherosclerosis is a major cause of mortality and morbidity, which is mainly driven by
complications such as myocardial infarction and stroke. These complications are caused by …

There is an increasing need for noninvasive methods that are able to monitor individual live
cells in vitro, including in vitro testing of chemicals and pharmaceuticals, monitoring the …
