Modified Luciferin Boosts Light Emission
By replacing a functional group in the firefly molecule luciferin, researchers have pumped up the intensity of light emitted by the luminescent molecule (J. Am. Chem. Soc., DOI: 10.1021/ja104525m). Fireflies light up the night, thanks to the luciferase-catalyzed reaction of oxygen and adenosine-5ʹ-triphosphate with D-luciferin to form an excited-state oxyluciferin molecule. When this molecule relaxes to its ground state, it gives off the . . .
