▎ 摘　　要

NOVELTY - The method involves preparing laser-induced graphene on the surface of a polyimide film (2) by using a laser engraving machine (1) to obtain a super-hydrophobic chip with a rose petal effect. An organic solvent is coated on portion of the surface of a laser-induced graphene (4) to obtain a super-hydrophobic chip with a lotus leaf effect. The adhesion performance of the lotus leaf effect area is lower than that of the rose petal effect area. The seamless assembly of a lotus leaf effect area and a rose petal effect area is realized by regulating and controlling the position and the area of organic solvent coating, so that the super-hydrophobic integrated chip with the lotus leaf effect-rose petal effect is formed. USE - Method for preparing bionic-based superhydrophobic integrated chip. Uses include but are not limited to chemical industrial analysis, environment monitoring, biological analysis and medical detection. ADVANTAGE - The method is simple. The prepared chip provides excellent super-hydrophobic property. The method can realize ultra-low concentration of analyte, ultra-high sensitivity and high speed detection. The lotus leaf effect area can realize non-destructive rolling, and uniform mixing and distribution of the droplet inner gold nano-particles and analyte molecules. The liquid drop is continuously evaporated in the rose petal effect area in the liquid liquid drop, and the enrichment of the gold nano particles and the analyte is realized. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a bionic surface enhanced Raman scattering (SERS) platform.
