(Nanowerk News) Instead of a pan and a pick ax, prospectors of the future might seek gold with a hand-held biosensor that uses a component of DNA to detect traces of the element in water. The gold ...

A chemist is developing inexpensive, portable and reusable sensors that use a component of DNA to detect gold, mercury, silver, lead and other metals. Instead of a pan and a pick ax, prospectors of ...

Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to ...

The idea of implantable sensors that continuously transmit information on vital values and concentrations of substances or drugs in the body has fascinated physicians and scientists for a long time.

(Nanowerk News) A thin, flexible gold sensor engineered at The University of Queensland (UQ) has the potential to unlock the next generation of implantable medical devices. Using a brand-new ...

What are the challenges for real-time biosensing and “edge” analysis? How do gold and gold-silver nanowires address the issue? How these sensors can implement elementary logic functions. Wearable ...

Detecting some cancers early can improve a patient’s chance of survival, but conventional detection methods can involve costly tests and equipment, making them inaccessible for people in low-resource ...
