Bio-inspired ultrasonochemical synthesis of blooming flower like ZnO hierarchical architectures and their excellent biostatic performance

Novel three dimensional (3D) ZnO hierarchical architectures were fabricated by a bio-inspired ultrasound assisted sonochemical route using self-sacrificial Aloe Vera (A.V.) gel as a bio-surfactant. The emergence of 3D superstructures (SS) is of essential interest, and the ability to program their form has practical ramifications in fields such as optics, biological activity, and catalysis and creates a bouquet of assembled SS with unprecedented levels of complexity and precision.
