Fabrication of nafion/silver nanoparticles/reduced graphene nanosheets /glucose oxidase nanobiocomposite for electrochemical glucose biosensing

The aim of this work was fabrication of a nanobiocomposite as a smart biosensor for monitoring glucose. a glucose nanobiosensor based on silver nanoparticles (sns) and reduced graphene nanosheets (rgns) composite was successfully fabricated and developed. the sns-rgns nanocomposites were successfully prepared and coated on the surface of strip. the reduced graphene nanosheets (rgns) support incorporated to zero-dimensional ag nanoparticles arrayed in the third dimension amended a glucose biosensor with superior sensing characteristics. the sensor abilities were certified by changing sensor performance (i.e.,sensitivity,limit of detection,and linear range) through using a novel nanocomposite. this approach to fabricate a biosensing device qualifies a high sensitive biosensor design that demonstrated outstanding biological sensing performance such as boosted glucose sensitivity (32 nm limit of detection,14.1 mam−1cm−2 sensitivity,200 nm to 9 mm linear sensing range),a long stable shelf-life (>21 days),and a high selectivity. to the best our knowledge,this device is the first biosensor protocol for glucose monitoring. © 2016 by cee (center of excellence in electrochemistry).
