was used in this study for further evaluation of the PA46 microstructure.
Researchers advise the use of gas chromatography/mass spectroscopy to supplement Raman spectroscopy
and develop more conclusive evidence of ancient extraterrestrial life.
According to a recent paper by the Marshalls in the peer-reviewed Philosophical Transactions of the Royal Society, by itself Raman spectroscopy
is able to screen for carbonaceous material, but it can't determine its source -- thus the technology needs to be supplemented in order to determine if life exists on Mars.
Recognized by the United States Pharmacopeia (USP) and the European Pharmacopoeia (EP) as a viable technique for compendial identification, Raman spectroscopy
is a non-destructive, reliable, efficient and cost effective method for the analysis of complex cell culture media.
was discovered in 1928 by Venkata Raman, who won a Nobel Prize two years later for his work.
, originally discovered by Indian physicist C.
is the only practical non-destructive way to distinguish the two minerals.
In the new study, Orringer and his colleagues used a revved-up version of Raman spectroscopy
, a technique that reveals vibrations of specific chemical bonds, to distinguish between proteins and lipids in brain tissue.
Using a technique called Raman spectroscopy
, which detects laser light, forensic investigators will be able to analyse lipstick marks left at a crime scene, such as on glasses, a tissue, or cigarette butts, without compromising the continuity of evidence as the sample will remain isolated.
This variant of Raman spectroscopy
allows highly accurate chemical analysis of objects beneath obscuring surfaces, thereby enabling the standoff identification of explosives inside opaque containers.
Researchers said that the technique, called Raman spectroscopy
(RS), which involves shining a light beam on to a sample of tissue to reveal any abnormalities, could be quicker and more reliable than the current biopsy method.
Now, an additional in vivo study using confocal Raman Spectroscopy
reinforces the previous findings.
