Surface-enhanced Raman scattering (SERS) is a powerful analytical method, which provide chemical fingerprint of single-molecule. Recently, many flexible and bendable SERS substrate is researched. researchers have made lot of effort, however, there is still a dilemma between gap distance and bendability or flexibility. In this research, we demonstrated the effect of AuNPs/MXene/AuNPs/wrinkled-PDMS system for flexible and bendable SERS substrate. The substrate performance is maintained in the bending situation to using PDMS wrinkle system, which maintain the gap distance of AuNPs, and the MXene was increase the SERS effect. Raman intensity of crystalviolet (C.V) dye on AuNPs/MXene/AuNPs/PDMS was not decrease when the substrate deformation. We expected this system to be use not only SERS substrate but also other optoelectronic device, biological and optical sensor. |
