Photo-triggered

Photo-triggered describes a process, event, or reaction initiated or activated by the presence, interaction, or change in light or photons. This can apply to various scientific disciplines, including biology, chemistry, and engineering. In essence, something undergoes a transformation or change because it absorbs light or responds to a specific wavelength or intensity of light. The effects of the light may involve physical alteration, chemical reactions, electronic changes, or even the creation of new products. The process necessitates an interaction between light and a light-sensitive material or system to produce a specific desired effect. Examples include light-activated switches, photo-responsive materials, and biological processes like photosynthesis and vision.

Photo-triggered meaning with examples

• A photo-triggered switch activates a circuit when exposed to a beam of light, acting as a basic form of remote control. This is used for applications from automatic lighting to the control of machinery, which demonstrates a change or effect due to a specific wavelength. This enables automated functionality in a range of everyday applications.
• Researchers developed photo-triggered drug delivery systems where medication is encapsulated in a light-sensitive material that releases the drug upon exposure to specific wavelengths of light. The use of light allows the medication to be accurately targeted only at the tissue to treat.
• In some art installations, photo-triggered sensors control the lighting and sound effects in response to changes in ambient light or the presence of viewers. It becomes reactive and interactive, with the output being directly linked with light changes in the environment.
• Photo-triggered chemical reactions are used in various industrial processes, such as the production of polymers. This ensures great precision and energy saving.
• The protein changes its form when a specific light shines on it. It then interacts with another protein to facilitate the movement. This is important in biological processes.
