| 中文摘要 | a novel kind of k+ sensor with valinomycin-incorporated bilayers supported on a gold electrode consisting of self-assembled alkanethiol monolayers (sams) and a lipid monolayer has been fabricated successfully. the lipid monolayer is deposited on the alkylated surface of the first alkanethiol monolayer through three different methods, such as the langmuir-blodgett (lb) technique, painted method and painted-frozen method. the response of k + sensors produced by a painted or painted-frozen lipid monolayer on an alkanethiol alkylated gold electrode is larger than that by the lb method, which is due to the difference in fluidity of the three kinds of bilayers. selectivity coefficients kk+, na+, kk+, li+, kk+, ca2+ and kk+, mg2+ are 10(-4), 10(-4), 2 x 10(-5) and 3 x 10(-5) respectively, and there is no obvious difference among different fabricating methods. a linear response toward the potassium ion was found in the range from 10(-1) m to 10(-5) m with the detection limit of 10(-6) m. the sensor has a slope of 60 mv per decade. meanwhile, the longevity of the sensor was improved obviously for at least two months at about -10 degrees c. the higher stability shows the possibility to fabricate a practical biosensor. |
