A near-infrared light-controlled, ultrasensitive one-step photoelectrochemical detection of dual cell apoptosis indicators in living cancer cells

The proposed near-infrared (NIR) light-controlled, one-step photoelectrochemical (PEC) strategy could simultaneously detect cell apoptosis indicators, phosphatidylserine (Pho) and sodium potassium adenosine triphosphatase (Sat), on living cancer cells.
