Testing wastewater samples is one of the primary methods for assessing infectious disease prevalence in populations. By collecting and testing samples from various water treatment plants, scientists ...

Researchers at the University of São Paulo (USP) in Brazil have developed a kraft paper-based electrochemical sensor that can detect traces of pesticides in fruit and vegetables in real time when ...

The COVID-19 pandemic introduced everyone to the world of PCR tests and lateral flow tests but since then, a different type of testing has quietly been gaining momentum. Wastewater testing is a ...

Researchers at the USC Viterbi School of Engineering looked to origami to create new sensors that could someday be employed to detect deformations in organs and also for use in wearables and soft ...

Scientists have invented a paper-like, battery-free, AI-enabled sensor patch -- PETAL -- for convenient and effective monitoring of wound recovery. This novel technology provides early warning of ...

Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far ...

They linger in our water, our blood and the environment—so-called "forever chemicals” that are notoriously difficult to detect. But researchers at the University of Chicago Pritzker School of ...
