The ultra race amount of amphetamine was efficiently measured using the fluorescence probe based on 8-hydroxyquinoline-beta-cyclodextrin. The absorption spectra were obviously proved the static enhancement mechanism of the probe under the response time, 50 s and solution pH, 6 as optimized conditions. 8-hydroxyquinoline-beta-cyclodextrin-graphene oxide (GO-CD-HQ) showed an excellent response to amphetamine in the linear concentration range (1-140) x 10(-5) M, with a notable detection limit 3.67 x 10(-5) M.
