New device for quick and accurate detection of lead

A research team from the Department of Chemistry of Hong Kong Baptist University (HKBU) has invented a portable device for one-stop detection of lead concentration in drinking water. The DNA-based device, which works together ...

Real-time coverage of inside of the brain made possible

Real-time monitoring of the dynamics of endogenous molecules in organisms is an important aspect in the study of diseases. However, this process is difficult because of issues such as sensitivity, resolution, and invasiveness. ...

Weighing single molecules with light

Scientists at Oxford University have developed a light-based measuring technique that could transform our ability to characterise biomolecules.

Why we need erasable MRI scans

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is through the use of contrast agents—magnetic dyes injected into ...

One step closer to reality

Diffusion is the process that lets the color spread through tea, but there is way more to it than that: It's also one of the most fundamental principles underlying the inner workings of living cells. The ability of molecules ...
