Light-activated anion pump
This light-activated pump, designed to both capture and release negatively charged ions, or anions, can move target molecules against a concentration gradient in solution, fueled only by natural light. The blue light on the right side shows the filtration and capture of chlorides and bromides by synthetic molecules the researchers designed to target specific pollutants.
[Research supported by U.S. National Science Foundation grant CHE 2304983.]
