Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

(Nanowerk Spotlight) Over the past few years, the development of materials that act as chemical paints (i.e. coatings) by responding to a (bio)chemical parameter with a change in their optical ...

In this article, we focus on the use of graphene in water sensors, exploring how these sensors detect common contaminants, including heavy metals, microbes and irregular pH. Various types of sensors ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without ...

Early-stage disease diagnosis relies on the highly sensitive detection of biomarkers. Optical whispering-gallery-mode (WGM) microcavity sensors have emerged as a highly promising technology for ...

Researchers at General Electric are set to begin research into how they can turn commonly-used surfaces into COVID-19-detecting devices, the company announced this week. The GE Research team has ...
