Biological effects of lasers have been reported for some time, yet the molecular mechanisms procuring cellular responses remain obscure. We show that mitochondria serve as sub-cellular “sensor” and “effector” of laser light non-specific interactions with cells. Our findings reveal the mechanism how laser irradiation interfere with cell homeostasis and underscore that such laser irradiation permits remote control of mitochondrial function in the absence of chemical or biological agents.
