The big antifreeze: Raman thaws out the science

Date: Aug 1, 2018

Author: David Bradley

Simulated Raman spectroscopy has provided new insights into how antifreeze proteins, which have been known about for decades, actually work to keep alive animals such as fish and insects despite many living in temperatures that would otherwise frees their bodily fluids.

Raman breath test: Detecting illicit drugs

Date: Jun 1, 2018

Author: David Bradley

An inexpensive and yet high-performance chip based on surface-enhanced Raman spectroscopy (SERS) can test for illicit drugs such as cocaine, opioids, and marijuana as quickly as a breathalyzer can detect alcohol.according to new research from the USA. The device can quickly reveal such drugs in for samples of blood, urine, saliva, and even on the breath.
