Abstract

A Cu O superstructure is constructed through a recrystallization-induced self-assembly strategy. Single Cu O superstructure particle exhibits an outstanding surface-enhanced Raman spectroscopy performance with the limit of detection as low as 10 mol L and metal comparable enhancement factor (8 × 10 ) due to the synergetic effect of vacancies defect-facilitated charge-transfer process and copper vacancies defect-induced electrostatic adsorption.
