Researchers at Kanazawa University monitored the emission of blue-green light from water-soluble tetraphenylethene molecules adsorbed at a phospholipid-adsorbed liquid-liquid interface made to resemble a biomembrane. They found that the process could be reversibly controlled by an externally applied potential (voltage), which opens the possibility for a new class of molecular probes and targeted drug delivery systems.
