Simple immersion to prepare a Zn/Ag biomimetic superhydrophobic surface and exploring its applications on SERS

- The as prepared Zn/Ag superhydrophobic surface exhibits a high contact angle (167°) and a low sliding angle (<2°).
- The preparation method is simple, low cost and easy to implement.
- CT-SERS was used to monitor the growth state of the silver on the Zn surface.
- The as prepared superhydrophobic surface was used for further improved the detection limit during the SERS analysis.
