聚合酶链式反应(PCR)是分子诊断的金标准。然而,SARS-CoV-2大流行表明,迫切需要新的诊断方法,为用户提供即时结果,而不需要复杂的程序或复杂的设备。这些新的需求激发了一股创新的海啸,这些创新在不影响特异性和敏感性的情况下缩短了周转时间,使PCR成为诊断的典范。在这里,我们简要介绍了聚合酶链式反应和等温扩增的起源,然后转向CRISPR-CAS和ArgAerte蛋白质的出现,它们被耦合到荧光仪、光谱仪、微流控设备、场效应晶体管和安培生物传感器,用于新一代基于核酸的诊断。
Polymerase Chain Reaction (PCR) is the reigning gold standard for molecular diagnostics. However, the SARS-CoV-2 pandemic reveals an urgent need for new diagnostics that provide users with immediate results without complex procedures or sophisticated equipment. These new demands have stimulated a tsunami of innovations that improve turnaround times without compromising the specificity and sensitivity that has established PCR as the paragon of diagnostics. Here we briefly introduce the origins of PCR and isothermal amplification, before turning to the emergence of CRISPR-Cas and Argonaute proteins, which are being coupled to fluorimeters, spectrometers, microfluidic devices, field-effect transistors, and amperometric biosensors, for a new generation of nucleic acid-based diagnostics.
