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.
