Using Renilla luciferase (“nano lantern”) and chemiluminescence, the group could image Ca2+, cyclic adenosine monophosphate and adenosine 5′-triphosphate dynamics in environments where the use of fluorescent indicators was not feasible. With this technology, cancer tissues of a mouse could be observed in vivo and real time at video rates.
