Researchers at the Indian Institute of Science (IISc) have developed a unique luminescent probe that uses terbium, a rare earth metal, to sense the presence of an enzyme called β-glucuronidase, which ...

Scanners for loose papers have become so commonplace that almost every printer includes one, but book scanners have remained frustratingly rare for non-librarians and archivists. [Brad Mattson] ...

Scientists at EPFL have created a revolutionary biosensor that doesn't need a light source—it makes its own glow using ...

Asylon, in partnership with 908 Devices, the Indianapolis Metropolitan Police Department, and the Indianapolis Motor Speedway, successfully deployed its innovative gas-sniffing security robots at the ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

The article describes the development of a versatile gas sensing platform using an Arduino UNO microcontroller. The system utilizes the widely available MQ3 gas sensor for practical applications in ...

The minimum detection limit of the PAS sensor was 14 ppb without enrichment and 1.3 ppb with enrichment, a record value for NO detection using PAS-based techniques. Applications ...

This detector circuit uses just the Arduino Nano itself, without an added sensor. It can detect air flows blown from a distance of 30 cm, by measuring the internal heated chip temperature with ...
