چکیده انگلیسی


• New sensor based on energy transfer from graphite oxide SAMs to silver nanoparticles;
• "OFF–ON" type fluorescent sensor for captopril with high signal to noise ratio;
• The novel detection platform demonstrated intriguing reusable properties.

In this work we designed a self-assembly multilayers, in which photoluminescent graphene oxide was employed as a fluorescence probe. This multilayers film can effectively recognize captopril by resonance energy transfer from graphite oxide to silver nanoparticles. A new interfacial sensing method for captopril with high signal to noise ratio was established, by means of that multilayers was quenched by silver nanoparticles and subsequently recovered by adding captopril. The linear relation between intensity and captopril concentration was good, and the detection limit was found to be 0.1578 μM. Also, this novel detection platform demonstrated intriguing reusable properties, and the sensor could be repeated more than ten times without obviously losing its sensing performance.
