About This Webinar
Optoacoustic spectroscopy, a technique originally established in the 19th century, is currently being leveraged to push boundaries in biomedical science. Research groups are making vast improvements to mid-infrared optoacoustic imaging and detection techniques that have yielded promising results for applications including both non-invasive glucose monitoring and label-free analytic histology.

Several biomolecules, such as glucose, lipids, and proteins, are excited by the high spectral brightness of quantum cascade infrared lasers (QCL-IR). Illuminating these biomolecules with a pulsed QCL-IR source operating in the “fingerprint” wavelength band causes acoustic waves to propagate via the photoacoustic effect. The combination of high spectral brightness, high wavelength-resolution, and low acoustic background enables researchers to collect highly detailed spectroscopic data at increased sample depths with improved signal-to-noise ratios. By coupling established techniques with modern technology, researchers have enabled the exploration of critical new applications in biomedical science.
