A novel two‐side‐activatable high‐performance surface‐enhanced Raman spectroscopy (SERS) substrate is developed based on the tape‐imprinting method. It features 3D full‐space‐distributed hot spots originating from the hierarchical lotus seedpod‐like silver arrays, which offer ultrasensitive, uniform, reproducible, and reliable quantitative measurements with an inherent internal standard. This excellent SERS substrate also holds great promise in practical in situ molecule detection on curved surfaces, such as pesticides on fruit, which is not yet possible with the traditional rigid or flexible material‐based SERS counterparts.
