Photoactivatable Fluorescence

Photoactivatable fluorescence refers to the ability of certain molecules to switch from a non-fluorescent (dark) state to a fluorescent (glowing) state when exposed to specific light. This property allows scientists to control when and where these molecules emit light, enabling detailed imaging of structures inside cells. By activating individual molecules sequentially, researchers can create high-resolution images beyond traditional limits, which is valuable in studying complex biological processes with great precision. This technique is widely used in advanced microscopy to visualize cellular components dynamically and with remarkable clarity.
