This study reports a simple, rapid, low-cost, robust, and multiplexed barcoded paper-based assay (BPA) compatible with mobile devices. An inkjet printer and an XYZ dispensing platform were used to realize mass-manufacturing of barcoded paper-based analytical devices (BPADs) with high precision and efficiency. We designed a new group of barcodes and developed an application (APP) for the reading of the new code. The new barcodes possess a 16 times higher coding capacity than the standard Codabar code in our experiment on drug residue detection. The BPA system allows applications in the assays of blood-transmitted infections, drug residues in milk and multiplex nucleic acids. The whole detection process and the readout of the results can be completed within 10 minutes. The limit of detection for enrofloxacin (ENR) (8 ng mL⁻¹) satisfies the requirements of drug residue monitoring. Its high rapidity, simplicity, efficiency and selectivity make the BPA system extremely suitable to be applied in rapid and on-site detection.

喷墨打印条形码，用于与移动设备兼容的快速，多种纸张检测

这项研究报告了一种与移动设备兼容的简单，快速，低成本，健壮和多路条形码条形码纸质化验（BPA）。喷墨打印机和XYZ分配平台用于以高精度和高效率实现条形码化纸质分析设备（BPAD）的批量生产。我们设计了一组新的条形码，并开发了用于读取新代码的应用程序（APP）。在我们的药物残留检测实验中，新条形码具有比标准Codabar码高16倍的编码能力。BPA系统可用于血液传播的感染，牛奶中的药物残留和多重核酸的检测。整个检测过程和结果的读出可以在10分钟内完成。恩诺沙星（ENR）（8 ng mL ^-1）满足药物残留监测的要求。它的高速度，简便性，效率和选择性使BPA系统非常适合用于快速和现场检测。
