Abstract

Synthesis of uniform and dense metal nanostructures on the whole exposed fiber, instead of simply on the membrane surface, is necessary for controllable separation and sensitive SERS detection. Herein, uniform and dense AuNP/MoS2 hybrids were synthesized on single 3D glass fiber (GF) surfaces, obtained by the reaction of a MoS2 nanosheet and HAuCl4. The chemical mechanism (CM) of the MoS2 layers and the electromagnetic enhancement (EM) of the dense AuNPs were used to enhance the SERS sensitivity. The molecule-separation ability of the obtained GF membranes, constructed by numerous compacted fibers with dense AuNP/MoS2 hybrids, was not destroyed, and herein, these membranes were used to separate mixed molecules. These MoS2-based hybrid substrates show great potential for excellent paper-based separation and are sensitive SERS substrates for biological and chemical detection.
