Virus sensing is earning great interest for recognition of dangerous and widely spread diseases, such as influenza A (virus subtypes H1N1, H3N2 etc), severe acute respiratory syndrome, Middle East respiratory syndrome etc. Many molecular and biological techniques have been developed and adopted for virus detection purposes. These techniques show some drawbacks concerning long collection time and data analysis, sensitivity, safety, costs etc. Therefore, new sensing approaches have been proposed for overcoming these limitations. In this short-review, we explore the emerging and challenging terahertz radiation technology and its applications to virus high-sensitivity remote-sensing devices.

病毒传感在识别危险和广泛传播的疾病方面引起了极大的兴趣，例如甲型流感（病毒亚型 H1N1、H3N2 等）、严重急性呼吸系统综合症、中东呼吸系统综合症等。许多分子和生物技术已被开发并应用于病毒检测目的。这些技术在收集时间长和数据分析、灵敏度、安全性、成本等方面存在一些缺点。因此，已经提出了新的传感方法来克服这些限制。在这篇简短的评论中，我们探讨了新兴且具有挑战性的太赫兹辐射技术及其在病毒高灵敏度遥感设备中的应用。
