ABSTRACT
A methylene blue (MB)-based beta-galactosidase (ß-gal) activatable molecule, Gal-MB, was developed for senescence imaging and light-triggered senolysis. When in contact with LacZ ß-gal or senescence-associated ß-gal (SA-ß-gal), the photoinsensitive Gal-MB becomes fluorescent. Gal-MB also offered selective phototoxicity toward LacZ ß-gal expressing cells and drug-induced senescent cells, which express SA-ß-gal, after light illumination at 665 nm.
