Chemical-responsive adhesive sensing chip is a new low-cost analytical platform that uses adhesive tape loaded with indicator reagents to detect or quantify the target analytes by directly sticking the tape to the samples of interest. The chemical-responsive adhesive sensing chips can be used with paper to analyze aqueous samples; they can also be used to detect and quantify solid, particulate, and powder analytes. The colorimetric indicators become immediately visible as the contact between the functionalized adhesives and target samples is made. The chemical-responsive adhesive sensing chip expands the capability of paper-based analytical devices to analyze solid, particulate, or powder materials via one-step operation. It is also a simpler alternative way, to the covalent chemical modification of paper, to eliminate indicator leaching from the dipstick-style paper sensors. Chemical-responsive adhesive chips can display analytical results in the form of colorimetric dot patterns, symbols, and texts, enabling clear understanding of assay results by even nonprofessional users. In this work, we demonstrate the analyses of heavy metal salts in silica powder matrix, heavy metal ions in water, and bovine serum albumin in an aqueous solution. The detection is one-step, specific, sensitive, and easy-to-operate.

低成本化学响应式粘合剂传感芯片

化学响应式粘合剂传感芯片是一种新型的低成本分析平台,该平台使用装有指示剂的胶带,通过将胶带直接粘贴到目标样品上来检测或量化目标分析物。化学响应型粘合剂传感芯片可与纸一起使用,以分析水性样品;它们还可以用于检测和定量分析固体,颗粒和粉末分析物。当在功能化粘合剂和目标样品之间进行接触时,比色指示剂立即可见。这种对化学反应敏感的粘合剂传感芯片可通过一步操作扩展纸基分析设备分析固体,颗粒或粉末材料的能力。这也是纸的共价化学改性的一种更简单的替代方法,消除指示器从量油尺式纸张传感器漏出的现象。化学响应性粘合芯片可以以比色点图案,符号和文本的形式显示分析结果,即使是非专业用户也可以清楚地了解分析结果。在这项工作中,我们演示了二氧化硅粉末基质中重金属盐,水中重金属离子和水溶液中牛血清白蛋白的分析。该检测是一步,特定,灵敏且易于操作的。和牛血清白蛋白的水溶液。该检测是一步,特定,灵敏且易于操作的。和牛血清白蛋白的水溶液。该检测是一步,特定,灵敏且易于操作的。
