In this work, a miniaturized, automated, and cost-effective ELISA device is designed and implemented, without the utilization of conventional techniques such as pipetting or microfluidic valve technologies. The device has dimensions of 24 cm × 19 cm × 14 cm and weighs <3 kg. The total hardware cost of the device is estimated to be approximately $1200, which can be further reduced through optimization during scale-up production. Three-dimensional printed disposable parts, including the reagent reservoir disk and the microfluidic connector, have also been developed. IL-6 is used as a model system to demonstrate how the device provides an ELISA measurement. The cost per test is estimated to be <$10. The compactness, automated operation, along with the cost-effectiveness of this ELISA device, makes it suitable for point-of-care applications in resource-limited regions.
在这项工作中，设计并实现了一种小型化、自动化且具有成本效益的酶联免疫吸附测定（ELISA）设备，无需使用诸如移液或微流控阀技术等传统技术。该设备尺寸为24厘米×19厘米×14厘米，重量小于3千克。该设备的硬件总成本估计约为1200美元，在扩大规模生产过程中通过优化可进一步降低成本。还开发了三维打印的一次性部件，包括试剂储存盘和微流控连接器。白细胞介素-6（IL-6）用作模型系统，以演示该设备如何进行ELISA测量。每次测试的成本估计低于10美元。这种ELISA设备的紧凑性、自动化操作以及成本效益，使其适用于资源有限地区的即时检测应用。
