photactivated
Photactivated describes systems, molecules, or processes that require exposure to light to become active. Activation can be reversible or irreversible and typically involves absorption of photons that promote electrons to excited states, triggering chemical reactions, conformational changes, or signaling events.
In chemistry and materials science, photactivation refers to the initiation of chemical or physical changes by
In biology, photactivated, or photoactivated, describes proteins and systems that change function when illuminated. Many photoreceptor
Applications of photactivation span research and medicine. In neuroscience, photoactivation enables targeted study and manipulation of
