Photochemically triggered reaction of glucose oxidase in a fused vesicle containing Malachite Green leuconitrile derivative

Glucose oxidase (GOD) was encapsulated in vesicles containing a photoionizable Malachite Green leuconitrile derivative (MGL). Subsequent UV irradiation of MGL afforded the fusion of GOD- and glucose-encapsulating vesicles and thus decreased the concentration of glucose in the vesicles. The time dependence of the vesicle fusion was studied using fluorescent probe molecules. This phototriggered fusion could be instrumental in the development of a system for the production of nanometer-sized bioreactors.
