Cryogenic single‐particle photoluminescence (PL) spectroscopy has been used with great success to directly observe the heterogeneous photophysical states present in a population of luminescent particles. Cryogenic electron tomography provides complementary nanometer scale structural information to PL spectroscopy, but the two techniques have not been correlated due to technical challenges. Here, we...
Ein Selenanalogon von Amino‐D‐luciferin wurde synthetisiert und als vom Enzym Glühwürmchen‐Luciferase akzeptiertes Substrat identifiziert. Aminoseleno‐D‐luciferin hat ein rotverschobenes Emissionsmaximum der Biolumineszenz bei 600 nm (siehe Bild) und ist für Biolumineszenz‐Bildgebungsstudien in lebenden Organismen geeignet.
