Abstract

The invention discloses a method for manufacturing a surface enhancement Raman scatting (SERS) substrate having ultra high performance. The method comprises the steps: firstly, selecting a cicada wing, a butterfly wing, a scarlet macaw feather or other biological micro structures as a basal plate, and simply cleaning, drying and shaping the biological micro structure basal plate; and then plating gold, silver or other precious metals on the biological micro structure basal plate by magnetron sputtering or ion beam sputtering or other precise film plating methods to produce the SERS substrate. The gap size of a micro-nano structure is precisely controlled by controlling the thickness of the plating film, and the micro-nano gap size can be controlled to be less than 10 nm. The manufactured SERS substrate has the outstanding advantages of large area, low cost, uniformity, environmental protection, ultra sensitivity, precisely controllable gap and the like. The environmental protection material is selected as the basal plate, the quite simple, mature and low-cost method is used for manufacturing the high performance SERS substrate which meets the needs of practical applications and theoretical researches, so that a powerful tool and a solid foundation are provided for the theoretical researches and the practical applications of an SERS effect.
