Textile based biosensors have garnered much interest in recent years. Devices woven out of yarns have the ability to be incorporated into clothing and bandages. Most woven devices reported in the literature require yarns that are not available on an industrial scale or that require modifications which are not possible in large scale manufacturing. In this work, commercially produced yarns are taken without any modification or cleaning, and developed woven textile diagnostic devices out of them. The yarn properties that are important to their function within the device have been characterised and discussed. The wicking ability and analyte retention of Coolmax yarns, developed to wick sweat in mass produced sportswear, are determined. The electrochemistry and functionalizability of Au coated multifilament yarns are investigated with no cleaning or treatment and are found to have as good a thiolate self‐assembled monolayer (SAM) coverage as cleaned Au disk electrodes. The feasibility of using these yarns is established off the shelf, with no cleaning, to make woven capillary force driven microfluidic devices and three electrode sensing devices. A proof of principle three electrode system capable of detecting clinically relevant concentrations of glucose in human sweat is reported.

将现成的纱线编织成纺织微全分析系统 (μTAS)。
近年来，基于纺织品的生物传感器引起了人们的极大兴趣。由纱线编织而成的设备能够融入衣服和绷带中。文献中报道的大多数编织设备需要的纱线无法在工业规模上获得，或者需要在大规模制造中无法实现的修改。在这项工作中，商业生产的纱线未经任何修改或清洁就被取出，并从中开发出机织纺织品诊断设备。已经表征和讨论了对其在设备内的功能很重要的纱线特性。Coolmax 纱线的芯吸能力和分析物保留能力被确定，该纱线开发用于在大量生产的运动服中吸汗。在没有清洁或处理的情况下研究了 Au 涂层复丝的电化学和功能性，发现硫醇盐自组装单层 (SAM) 覆盖率与清洁的 Au 盘电极一样好。使用这些纱线的可行性是现成的，无需清洁，即可制作编织毛细管力驱动的微流体设备和三电极传感设备。报告了一种能够检测人体汗液中临床相关葡萄糖浓度的原理三电极系统的证明。
