A portable infrared spectrometer could significantly enhance biochemical sensing in the field
The infrared (IR) range of the electromagnetic spectrum is useful for imaging biological samples. Near-IR is used in night-vision cameras, far-IR in thermal cameras, and mid-IR for non-destructive spectroscopic analysis of molecular structures in biochemical samples. While the first two technologies are now simple and portable, mid-IR spectrometers remain bulky and expensive. Their widespread utility in analysis of samples in solid, liquid, or gas form for environmental studies, engineering analysis, and biomedical applications highlights the need for and commercial potential of a field-accessible model. POCSEL is developing just such a portable and inexpensive spectroscopic biochemical sensor for point-of-care medical diagnostics, food safety, and environmental monitoring. The pioneering device could have significant downstream impact on human health and safety.
