Integrating functional self‐propelled Zinc micromotors are created by coup­ling electrodeposition with hard dual‐templating synthesis. The micromotors concurrently possess four robust functions including a remarkably high loading capacity, combinatorial delivery of cargoes, autonomous release of encapsulated payloads, and self‐destruction. This concept could be expanded to simultaneous encapsulation of various payloads for different functionalities such as therapy, diagnostics, and imaging.

In 3+ doped Cu 2Àx Se nanostructures have been successfully synthesized on a flexible carboxyl functionalized multi-walled carbon nanotubes/polyimide (COOH-MWCNTs/PI) membrane substrate by an electrochemical codeposition method. In this work, the focus was on the effect of different In 3+ doping concentrations upon the morphological, structural, optical and photoelectrical properties of Cu 2Àx Se. Two different kinds of nanostructures, nanoflowers and nanolayers, were obtained. The crystallinity of Cu 2Àx Se was improved by doping with In 3+ . The atomic ratio of Cu, Se in Cu 2Àx Se nanolayers is about 1.85 : 1.00, and the atomic % of In is 1.32, confirming the presence of indium. The optical absorption intensity increased with an increase in the doping content of indium ions. However, In 3+ had no effect upon the band gap and absorption edge. The effect of In 3+ dopant on the photoelectric properties was investigated by photocurrent-time and current-voltage (I-V) measurements, which demonstrated that the photoelectric properties of Cu 2Àx Se were improved by doping with In 3+ . This result is significant for the fabrication of optoelectronic nanomaterials and photodetectors based on In 3+ -doped Cu 2Àx Se nanoflowers and nanolayers.
