'Green chemistry' to quantify the components of cosmetics

Right now, there are 10,000 components that can be used to make cosmetics. These components have to be monitored to guarantee consumer safety. The UPV/EHU researcher Josu López has developed three 'green' analytical methods ...

Devices designed to identify pathogens in food

Researchers at the National Polytechnic Institute (IPN) in Mexico have developed a technology capable of identifying pathogens in food and beverages. This technique could work in the restaurant industry as a biosensor to ...

New test detects drug use from a single fingerprint

Research published today in the journal Analyst has demonstrated a new, noninvasive test that can detect cocaine use through a simple fingerprint. For the first time, this new fingerprint method can determine whether cocaine ...

Opening a wide window on the nano-world of surface catalysis

(Phys.org) —Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information from Ag nanocatalysts ...

Optical techniques examine toxic agents in cells

EPFL researchers have developed a method for accurately determining the toxicity of nanomaterials. By using optical techniques, they are able to measure the concentration of the oxidizing substances produced by a damaged ...
