Abstract
Flexible SERS substrate would offer a highly sensitive and rapid means for detecting ultra-low concentration of analytes on an irregular surface, enabling its arising applications in wearable and wipeable devices. Here we launched a fabrication method by using Archimedes' Principle to produce a flexible and low cost SERS substrate, which carries Ag nanoparticles. Our study could effectively implement flexible SERS practice and could be extended for future applications in flexible sensors and actuators.
