Recent progress in the preparation of AuNPs-PDMS composite membranes

Gold nanoparticles-dimethylsiloxane （AuNPs-PDMS） membrane is a novel composite material in biochemical tech- nology and micro-electro-mechanical system （MEMS） research. It is widely used in biomedicine, biochemical detection and environmental protection due to its biocompatibility, elasticity and electric characteristics. In this paper, the characteristics of the composite membrane were described, and four methods for fabricating AuNPs-PDMS composite membranes were reviewed in detail. Besides, the advantages and disadvantages of the four methods were summarized, and the present problems and future researches were proposed.
