    The design of photoactivatable fluorophores—which are required for some super-resolution fluorescence microscopy methods—usually relies on light-sensitive protecting groups imparting lipophilicity and generating reactive by-products. Now, it has been shown that by exploiting a unique intramolecular photocyclization, bright and highly photostable fluorophores can be rapidly generated in situ from appropriately substituted 1-alkenyl-3,6-diaminoxanthone precursors.

    Lipid membranes—which separate cells and organelles from their environment—experience tension during various cell processes; however, measuring membrane tension is notoriously difficult. Now, a new fluorescent, mechanosensitive membrane probe called FliptR has been developed. FliptR enables simple, direct membrane tension measurements in cellular and artificial membranes.
