A team of researchers has developed a new biosensor that turns the invisible signals into visible color changes to detect urea levels in a simple way. The sensor works by combining gold nanoparticles ...

Detecting cancer in the earliest stages could dramatically reduce cancer deaths because cancers are usually easier to treat when caught early. To help achieve that goal, MIT and Microsoft researchers ...

The sensor can detect urea down to 0.098 µM in solution and 0.2 µM in solid form. It significantly outperforms traditional methods and performed well in real urine samples, opening new possibilities ...
