The human body is engaged in a constant tightrope walk to maintain the right pH, because when our cells' acid-alkaline balance goes wrong, it can go wrong in a big way. Abnormal pH - in particular, ...

pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...

The illustration is a summary map of the organellar pH measured with a single pH-sensitive probe, SITE-pHorin, which possesses an ultra-pH sensitivity enhanced by the quantum entanglement effect. As ...

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.

Figure 1: Mechanism of a cancer imaging strategy using target-specific activatable probes. To overcome this problem, we developed an activatable fluorescence probe consisting of a cancer-targeting ...
