Water contamination by harmful metals is a big deal, especially in places where fancy labs are scarce. Think about it: traditional ways to spot these metals, like atomic absorption spectrometry and inductively coupled plasma mass spectrometry, are super accurate but come with a hefty price tag and a steep learning curve. Plus, they are not exactly portable. This is w...

The Liujiang River Basin in China faces a serious problem with toxic metals. These metals, which are harmful to both the environment and human health, come from various sources.

Imagine if you could easily spot toxic metals in water, like chromium and manganese, just by watching the water change color. Well, scientists have made this possible with a new nanocarbon hydrogel kit. This smart material can detect these metals in just 10-15 minutes, and it’s so sensitive that it can find tiny amounts, like 0. 28 and 0. 30 micrograms per milliliter...
