Scanning electron micrograph of (a) A silver-coated capillary tip as PDT device. (b) Homogeneous layer grown on ZnO thin film model on silver coated femtotip capillary. (c) SEM image of ZnO nanowires on the silver-coated capillary tip having a scale range of 1 μm with the inset showing the hexagonal ZnO nanowires. (d) SEM images magnified from a selected area of ZnO NWs grown on a femtotip capillary having a scale range of 1 μm for deep emission photodynamic therapy.
