These schematic drawings show how researchers applied laser pulses to HCN channels tagged with a fluorescent photosensitizer to observe the effects on these channels of singlet oxygen, a highly reactive form of oxygen that plays a role in a range of biological processes including photosynthesis and skin cancer / aging.

The path to clinical use could be short, he suggests, because I124 - chlor is based on a FDA - approved photosensitizer developed at Roswell Park, and the new technique employs widely available PET and endoscopic technology. (roswellpark.org)
