| 英文摘要 | Si nanowires (sinws) were covalently modified by fluorescence ligand, n-(quinoline-8-yl)-2-(3-triethoxysilyi-propylamino)-acetamide (qioet) and finally formed an optical sensor to realize a highly sensitive and selective detection for cu(ii). the qioet-modified sinws sensor has sensitivity for cu(ii) down to 10(-8) m, which is more sensitive than qioet alone. metal ions interferences have no observable effect on the sensitivity and selectivity of oloet-modified sinws sensor. the sinws-based fluorescence sensor is reversible by addition of acid to replace cu(ii). the sensing mechanisms of qioet-modified sinws to cu(ii) and the rationale for the increase in sensitivity and selectivity of qioet-modified sinws over qioet on cu(ii) are discussed. the current sensor structure may be extendable to other chemo- and biosensors, and even to nanosensors for direct detection of specific materials in intracellular environment. |
