Portable gas detection shrinks to new dimensions

A sensor for detecting toxic gases is now smaller, faster and more reliable. Its performance sets it up for integration in a highly sensitive portable system for detecting chemical weapons. Better miniature sensors can also ...

New nerve gas detector built with legos and a smartphone

Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders ...

Rapid detection of toxic compounds

NUS chemists have developed highly selective and sensitive sensors based on molecularly imprinted polymers (MIPs) for the rapid onsite detection of toxic agents.

Researchers greenlight gas detection at room temperature

Russian researchers have developed a mechanism for detecting molecular hydrogen using green light to illuminate a nanocrystalline composite sensor based on zinc and indium oxides. This enables a gas sensor operating at room ...

New med-tech zinc sensor developed

A new zinc sensor has been developed by researchers, which will allow for a deeper understanding of the dynamic roles that metal ions play in regulating health and disease in the living body.

Affordable lead sensor for home, city water lines

A new electronic lead sensor, potentially costing around $20, could keep an eye on home and city water quality, alerting residents and officials to the presence of lead within nine days. University of Michigan researchers ...

From battery waste to electrochemical sensor

Multiplex detection of antioxidants / food additives / preservatives in food samples is possible using our newly developed graphite-based nanocomposite electrochemical sensor from used alkaline battery. The chemical sensor ...
