The paper describes an integtrated sensor system that can selectively and reversibly detect sulfur derivatives in the presence of interferent molecules. This is accomplished by integrating analyte-specific sensing materials with optimized filter materials. Microfabricated quartz tuning fork arrays are used to provide fast, accurate and low-cost transduction of the analyte binding events into electronic signals. The concept is demonstrated for detection of three sulfur derivatives - dimethyl disulfide, ethanethiol and methylsulfide.
本文描述了一种集成传感器系统，该系统能够在存在干扰分子的情况下选择性且可逆地检测硫衍生物。这是通过将分析物特异性传感材料与优化的过滤材料相结合来实现的。微加工石英音叉阵列用于将分析物结合事件快速、准确且低成本地转换为电信号。该概念通过检测三种硫衍生物——二甲基二硫、乙硫醇和甲硫醚得到了验证。
