Abstract

We developed an innovative 3D printed casing that incorporates a lateral-flow immunoassay, dehydrated signal enhancement reagents, and a sealed buffer chamber. With only the push of a button for signal enhancement, our device detected the SARS-CoV-2 N-protein in 40 min at concentrations as low as 0.1 ng mL in undiluted serum.

摘要

我们开发了一种创新的 3D 打印外壳，其中包含侧向流动免疫分析、脱水信号增强试剂和密封的缓冲室。只需按下按钮增强信号，我们的设备就能在未稀释的血清中低至 0.1ng/mL 的浓度下在 40 分钟内检测到 SARS-CoV-2 N 蛋白。
