Abstract:
Objective To explore the performance of the novel nitric oxide(NO) electrochemical microsensor based on Au nano-particles(nano-Au) modified glass-fiber .Methods With columnar glass-fiber as the substrate material ,the in-situ chemical seed-growth technology was adopted to fabricate one kind of electrochemical microsensor based on gold nanoparticles pole electrodes and the amperometric response method was used to investigate the various properties of the NO microsensor .Results This microsensor had high sensitivity response to NO ,its linear range was 7 .2 nmol/L -11 .7μmol/L(r=0 .998) with a detection limit of 3 .6 nmol/L .Conclusion A novel electrochemical microsensor based on nano-Au pole electrode was fabricated .The NO microsensor posseses high sensitivity ,wide linear range ,good reproducibility and excellent anti-interference ability .
