How sensors are driving predictive maintenance. How maintenance is traditionally performed and the importance of moving to a data-driven approach. An overview of how sensors are the eyes and ears of ...

A quick and simple fluorescent test can detect trace quantities of benzene in both liquid and vapor form. The new test uses paper strips impregnated with a supramolecular host-guest assembly system ...

Not all poisonous gases have a smell or a color. But a tiny grid of pastel- and candy-colored squares that effectively “sniffs” out hazardous chemicals in the air such as chlorosarin — a highly toxic ...

Environmental contaminants like fluoride, lead, and pesticides exist all around and even within us. While researchers have simple ways to measure concentrations of such contaminants inside lab ...

A team of researchers has developed a new biosensor that turns the invisible signals into visible color changes to detect urea levels in a simple way. The sensor works by combining gold nanoparticles ...
