Optical photothermal infrared spectroscopy (O-PTIR): a promising new tool for bench-top analytical palaeontology at the sub-micron scale
This paper introduces O-PTIR as a new technique for analyzing organic fossils at the sub-micron scale, showing it can resolve molecular composition heterogeneities in 400 million-year-old fossils.
