Researchers in Purdue University's College of Engineering have invented and are developing noninvasive medical devices to make the monitoring and treatment of certain physiological and psychological ...

Scientists at Bath, have introduced a breakthrough carbon-based sensor for detecting lactic acid levels in saliva—avoiding the need for an electrical power source. The researchers, working in ...

Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store. When plants are infected by pathogens, suffer from a lack of water or ...

The composition of sweat makes it a valuable diagnostic fluid. While it is mostly water, the small fraction containing electrolytes, metabolic byproducts, and chemical traces can reveal important ...

Wearable biosensors are revolutionizing point-of-care diagnostics by offering real-time monitoring of physiological metrics and biomarkers. A team of researchers at Purdue University’s College of ...

Fluorescent boronic acid-based sensors exploit the reversible covalent interaction between boronic acid moieties and vicinal diols, a structural motif ubiquitous in saccharides. Upon formation of a ...

An Indian research team has designed a polymer film-modified glassy carbon (GC) electrode that can selectively detect folic acid (FA), a B vitamin and essential compound of human blood 1. Decreased ...

Scientists have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power. Scientists at ...

Researchers in Purdue University’s College of Engineering have created new noninvasive, wearable sensors that monitor levels of uric acid in human sweat. A paper about the research has been published ...

Climate change is causing increased flooding and prolonged waterlogging in northern Europe, but also in many other parts of the world. This can damage meadow grasses, field crops or other plants - ...
