英文摘要	Thanks to their outstanding properties and a wide range of promising applications, the development of a versatile and convenient preparation method for metallic copper nanocrystals with controllable shape is of primary significance. Different from the literature that utilized a capping agent bearing only one kind of Cu binding functionality, either an amino or a carboxylic unit, for their preparation and shape control, this contribution reports a convenient method to engage both amino and carboxylic binding units at the same time. In this method, natural amino acids have been chosen as capping agents and demonstrated their versatile capabilities for the preparation of both Cu nanoparticles and nanowires. Detailed X-ray photoelectron spectroscopy revealed that the binding mode between amino acids and the Cu surface is highly dependent on their chemical structures. Interestingly, the produced Cu nanocrystals, exhibited an extraordinarily excellent anti-oxidation power. Furthermore, it was found that the multiple functionalities of amino acids not only have a great impact on the properties of their capped nanocrystals, such as solvent dispersibility, but also provide a convenient route for their further modification and functionalization.
