'Biochemical Nose' Targeted for Home Sensing Market

Facebook X LinkedIn Email
A "biochemical nose" based on Raman spectroscopy can quickly and accurately detect or diagnose substances at the molecular level for applications in food safety, medical diagnosis, chemical analysis and even home safety. "Our system can do chemistry, biology, biochemistry, molecular biology, clinical diagnosis and chemical analysis," said Fanqing Frank Chen, president and cofounder of Optokey Inc., a Lawrence Berkeley National Laboratory spinoff that developed the technology. The device uses a microfluidic control system for lab-on-a-chip automated liquid sampling. Nanoplasmonic...Read full article

    raman spectroscopy
    Raman spectroscopy is a technique used in analytical chemistry and physics to study vibrational, rotational, and other low-frequency modes in a system. Named after the Indian physicist Sir C.V. Raman who discovered the phenomenon in 1928, Raman spectroscopy provides information about molecular vibrations by measuring the inelastic scattering of monochromatic light. Here is a breakdown of the process: Incident light: A monochromatic (single wavelength) light, usually from a laser, is...
