Carotenoid pigments provide some of the most common exclusively biogenic markers on Earth, and these organic pigments may be present in extraterrestrial life. Raman spectroscopy can be used to identify […]
We investigated the potential of a laser selection in the broad optical range, from ultraviolet through visible to infrared (excitation wavelengths of 325, 532, 785, and 1064 nm) for combined analysis […]
Little green men it isn’t — but a new study co-led by a Pitt PhD candidate shows the potential for a variety of carbon-based molecules in a crater on Mars. […]
Researchers have suggested that the condensation of low-molecular-weight aldehydes under basic conditions (e.g., pH > 11) is the prebiotic reaction responsible for the abiotic formation of carbohydrates.

The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to […]
Easy to use Raman sensor for numerous applications – Traditional micro-Raman systems are capable of performing fine-scale mineralogy; but these are used for in situ analysis. Most of the micro- […]
