Zika virus (ZIKV) and dengue virus (DENV) are highly contagious and lethal mosquito-borne viruses. Global warming is steadily increasing the probability of ZIKV and DENV infection, and accurate diagnosis is required to control viral infections worldwide. Recently, research on biosensors for the accurate diagnosis of ZIKV and DENV has been actively conducted. Moreover, biosensor research using DNA nanotechnology is also increasing, and has many advantages compared to the existing diagnostic methods, such as polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). As a bioreceptor, DNA can easily introduce a functional group at the 5' or 3' end, and can also be used as a folded structure, such as a DNA aptamer and DNAzyme. Instead of using ZIKV and DENV antibodies, a bioreceptor that specifically binds to viral proteins or nucleic acids has been fabricated and introduced using DNA nanotechnology. Technologies for detecting ZIKV and DENV can be broadly divided into electrochemical, electrical, and optical. In this review, advances in DNA-nanotechnology-based ZIKV and DENV detection biosensors are discussed.
寨卡病毒(ZIKV)和登革热病毒(DENV)是极具传染性和致命性的蚊媒病毒。全球变暖正稳步增加寨卡病毒和登革热病毒感染的可能性,因此需要准确诊断以控制全球范围内的病毒感染。最近,针对寨卡病毒和登革热病毒准确诊断的生物传感器研究正在积极开展。此外,利用DNA纳米技术的生物传感器研究也在增加,与现有的诊断方法(如聚合酶链反应(PCR)和酶联免疫吸附测定(ELISA))相比具有许多优势。作为生物受体,DNA可以很容易地在5'或3'末端引入官能团,也可以用作折叠结构,如DNA适配体和DNA酶。利用DNA纳米技术制备并引入了一种能与病毒蛋白或核酸特异性结合的生物受体,而不是使用寨卡病毒和登革热病毒抗体。检测寨卡病毒和登革热病毒的技术大致可分为电化学、电学和光学技术。在这篇综述中,将讨论基于DNA纳米技术的寨卡病毒和登革热病毒检测生物传感器的进展。
