Photoactivation

Photoactivation is a technique where light energy is used to activate or trigger a specific process in a material or biological system. In medicine or research, it often involves shining targeted light (usually lasers or specific wavelengths) on a substance or tissue to initiate a reaction, such as releasing a drug or activating a fluorescent marker. This method allows precise control over when and where the process occurs, enabling detailed studies or targeted treatments without affecting surrounding areas. Essentially, photoactivation uses light as a switch to control activity in a controlled, localized manner.
