Mid-infrared spectroscopy can identify the molecular composition of unknown samples by their “fingerprints” at different wavelengths, allowing scientists to look beyond visible light’s band within the electromagnetic spectrum. The resulting compositional data is valuable for analyzing chemical and biological samples; however, the technology is generally confined to large instruments in research laboratories—limiting its accessibility and reach.
