Review of life science applications using submicron O-PTIR and simultaneous Raman microscopy: a new paradigm in vibrational spectroscopy

The recent advent of Optical Photothermal IR (O-PTIR), has enabled for the first time, submicron infrared microscopy in far-field reflection mode with the combination of Raman for simultaneous, correlative IR+Raman microscopy. These unique and exciting synergistic capabilities are now spawning interest in life science application [1-2]. A broad range of life science applications, otherwise impossible with traditional FTIR/QCL microscopy, will be...
