Pocket-sized invention revolutionizes ability to detect harmful materials

The low-cost cellphone-based Raman spectrometer system can make identifications of unknown biological molecules within minutes

18-Jul-2024 - Imagine knowing what berry or mushroom is safe to eat during a hike or swiftly detecting pathogens in a hospital setting that would traditionally require days to identify. Identification and detection of drugs, chemicals and biological molecules invisible to the human eye can be made possible ...

Novel Raman technique breaks through 50 years of frustration

04-Aug-2023 - Raman spectroscopy — a chemical analysis method that shines monochromatic light onto a sample and records the scattered light that emerges — has caused frustration among biomedical researchers for more than half a century. Due to the heat generated by the light, live proteins are nearly destroyed ...

Researchers dramatically downsize technology for fingerprinting drugs and other chemicals

Tiny photonic chip could fit comfortably within the tip of a finger

01-Sep-2020 - As new infectious diseases emerge and spread, one of the best shots against novel pathogens is finding new medicines or vaccines. But before drugs can be used as potential cures, they have to be painstakingly screened for composition, safety and purity, among other things. Thus, there is an ...
