Front Cover: The Lucigenin Assay: Measuring Anion Transport in Lipid Vesicles (Anal. Sens. 2/2024)

The Front Cover picture shows liposomes with a fluorescent probe encapsulated to study the transmembrane transport of anions across the liposomal membranes by synthetic anion transporters. The positively charged probe lucigenin or the zwitterionic probe bis(3-sulfopropyl)-9,9’-biacridine (SPBA) can be used for this purpose. This work details how the quenching of these probes can be monitored by fluorescence spectroscopy to study the transport of chloride and other anions. Cover design by Dr. Aaron Torres-Huerta. More information can be found in the Concept article by Hennie Valkenier and co-workers.
