One can utilize light illumination to stimulate mitochondrial reactive oxygen species production through the use of mitochondria-specific photosensitizers. By proper tuning of the light dosage, the methodology permits probing of a multitude of mitochondrial damage responses, including mitophagy. This light-controllable trick offers unique opportunities for the investigation of mitophagy-one can spatiotemporally define mitochondrial damage, alter the number of impaired mitochondria, as well as modulate the severity of the mitochondrial injury. This light-activated mitophagy can be adapted not only to single-cell imaging techniques but also to cell population-based biochemical assays.
