摘要

分子诊断是确定传染病的金标准方法。从目标病原体中提取 DNA 是准确分析致病病原体的最重要步骤之一。本研究利用数字光处理-立体光刻（DLP-SL）技术开发了一种新型 3D 打印电泳 DNA 提取微型装置（3D-EDEM），用于护理点分析。3D-EDEM 由一个用于细菌裂解液容器的源室、一个用于洗脱溶液容器的汇室、一个包含毛细管通道的水凝胶通道（毛细管通道用作基于粒度分离的筛分基质）和两个用于提供电流的电极支架组成。在制造 3DEDEM 之前，先用聚乙二醇二丙烯酸酯 (PEG-DA)、Irgarcure 819 (IRG) 和 2-isopropyl thioxanthone (ITX) 分别作为单体、光引发剂和光敏剂制备紫外线固化树脂。三维打印的 3D-EDEM 具有成本低廉、可重复性好、使用方便等诸多优点，与软光刻法相比，更适用于现场提取 DNA 的微型装置。在3D-EDEM上提取DNA时，将大肠杆菌O157:H7（E. coli）裂解液和洗脱缓冲液分别装入源室和汇室。为评估 DNA 提取性能，特别是使用便携式电池提取 DNA 的性能，对 3D-EDEM 的最佳 DNA 提取时间和极限进行了测试。此外，从人工感染的食品样本中成功提取 DNA 的测试证实了 3D-EDEM 在实际领域的适用性。拟议的 3DEDEM 可用于临床诊断、食品安全、环境监测和法医分析领域的现场 DNA 提取。

3D-printable electrophoretic DNA extraction microdevice for on-site bacterial DNA recovery

Molecular diagnosis is a gold standard method for identifying an infectious disease. DNA extraction from a target pathogen is one of the most important procedures for accurate analysis of the disease-causative pathogen. In this study, a novel 3D-printed electrophoretic DNA extraction microdevice (3D-EDEM) was developed using a digital light processing-stereolithography (DLP-SL) for point-of-care analysis. The 3D-EDEM consists of a source chamber for a bacteria lysate reservoir, a sink chamber for an elution solution container, a hydrogel channel embracing capillary channels that act as a sieving matrix for size-based separation, and two electrode holders for supplying electrical current. Prior to fabricating the 3D-EDEM, UV-curable resin was prepared by using a poly(ethylene glycol) diacrylate (PEG-DA), Irgarcure 819 (IRG), and 2-isopropyl thioxanthone (ITX) as a monomer, a photoinitiator, and a photosensitizer, respectively. The 3D-printed 3D-EDEM provides numerous merits of being inexpensive, reproducible, and convenient, making it more suitable for on-site DNA extraction microdevices than soft-lithographic procedures. For DNA extraction on the 3D-EDEM, Escherichia coli O157:H7 (E. coli) lysate and elution buffer were loaded into the source chamber and the sink chamber, respectively. The optimum DNA extraction time and limit of the DNA extraction test of 3D-EDEM were carried out to evaluate DNA extraction performance, especially using a portable battery. Additionally, the successful DNA extraction test from artificially infected food samples confirms the applicability of the 3D-EDEM to real fields. The proposed 3D-EDEM is adequate for on-site DNA extraction in the field of clinical diagnosis, food safety, environmental monitoring, and forensic analysis.
