(Nanowerk Spotlight) Inside a wound, a complex chemical battle unfolds. As healing progresses, the wound environment shifts between acidic and basic states, each change signaling different stages of ...

The inside of a living cell is a surprising patchwork of environments. For example, pH levels can vary dramatically in different organelles, despite them being just a couple hundred nanometers apart.

In a recent study published in Scientific Advances, researchers created a bioresorbable, cordless, passive sensor that monitors pH locally and detects stomach leakage early on. Study: Bioresorbable, ...
