photobleaching
photobleaching
Noun
In scientific contexts, specifically fluorescence microscopy, this term describes an irreversible chemical destruction of a fluorophore. It is viewed as a technical limitation or a source of signal decay, contrasting with "quenching," which can be reversible. The term carries a negative connotation in research because it limits the duration of observation.
In industrial or textile contexts, the term refers to a deliberate process of decolorization. Here, the connotation is neutral or positive, describing a controlled method of achieving a specific aesthetic or functional result through light exposure.
