Fluorescent probes for pH sensing in living cells have emerged as indispensable tools in both fundamental biological research and clinical diagnostics. These probes employ a diverse array 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.

When you see a project with a digital display these days, you’ll be forgiven for assuming that there’s some kind of microcontroller behind the scenes. And while that’s often the easiest way to get a ...
