When a molecule of resazurin dye (on top of the particle) binds to the gold nanoparticle it is changed to highly fluorescent resorufin (in front of the particle) by removal of an oxygen atom (moving away to the right). Resorufin glows under ultraviolet light. A graph of the time it spends before releasing from the gold surface reveals details about how the reaction takes place. Graphic by Aleksandr Kalininskiy
