Morphology, photocatalytic and antibacterial activities of radial spherical ZnO nanorods controlled with a diblock copolymer

► The size of radial spherical ZnO nanorods reduces as a function of the stabilizer concentrations. ► The photodegradation efficiency of MB increases with an increasing of the surface area. ► A radial spherical ZnO nanorods show antibacterial activity against Escherichia coli and Staphylococcus aureus.
