Gold nanorods (GNRs) Janus membranes have been synthesized with

thiol-terminated polyethylene glycol (PEG-SH) and thiol-terminated

polystyrene (PS-SH) at the oil/water interface by modified self-assembly

strategy. Compared with conventional GNRs membrane, these membranes

exhibit significant surface plasmon resonance (SPR) peaks and an obvious

blue shift with the addition of PEG-SH or PS-SH. Moreover, the

Surface-enhanced Raman scattering

(SERS) performance and reproducibility of the GNRs Janus membranes have

been improved significantly. This indicates GNRs Janus membranes have

great application prospects in optical applications such as

science-based optical sensor design and SERS sensitive detection.
