Anal Chem:重磅炸弹!“造纸机”上检测疾病,成本仅需2美金!

2015-07-27 sunshine 译 MedSci原创

近日,由哈佛大学的科学家研究的“paper machine”能够检测出癌症、传染病以及某些遗传性疾病,而其成本竟低到了2美金。该研究成果在线发表于Analytical Chemistry。目前尽管基于特异性核酸序列引物扩增的临床试验已具备很高的敏感性和特异性。但是,这些检测方法的复杂性和昂贵费用限制它们的推广而仅集中在实验室研究使用,在检测疾病上并不能发挥其全部潜力。本文介绍了一种设备,集成了样品

近日,由哈佛大学的科学家研究的“paper machine”能够检测出癌症、传染病以及某些遗传性疾病,而其成本竟低到了2美金。该研究成果在线发表于Analytical Chemistry。

目前尽管基于特异性核酸序列引物扩增的临床试验已具备很高的敏感性和特异性。但是,这些检测方法的复杂性和昂贵费用限制它们的推广而仅集中在实验室研究使用,在检测疾病上并不能发挥其全部潜力。

本文介绍了一种设备,集成了样品制备和环介导等温扩增与使用手持式的紫外光源和智能电话的终端检测。该设备集合了微流控(允许流体处理)和多通道的优势,就像一台“造纸机”,允许中央图案纸带滑进/出射流路径,从而允许样品进入,洗涤缓冲,放大混合液,并使用最小的移液检测试剂,可手持,为一次性设备,可用于资源有限的情况下快速检测。该装置可创建一个动态密封状态,以防止孵化期间(65°C下1小时)样品的蒸发。而1小时足以对大肠埃希菌malB基因进行LAMP扩增,且分析的灵敏度未1条双链DNA目标副本。

本研究将活的大肠杆菌加入人血浆中,演示了整个操作流程,其检测极限为5个大肠杆菌。此外,它表明,即使是指尖血,本研究样品的制备方法也可其DNA的浓度达到要求。


过程如下:



简明步骤:

1.加入微流态的样品;

2. 加入缓冲剂(Buffer);

3.加入混合后的LAMP试剂,孵育;

4.再加入SYBR Green I,在紫外照射透视下观察。
