回音壁模式（WGM）谐振器受到了广泛的关注，其独特的特性导致了一些令人瞩目的成就。特别是，当与光学传感技术相结合时，基于WGM重离子体的传感器具有尺寸小、灵敏度高和实时动态响应的优点。目前，这类传感器广泛应用于生化传感领域。本文综述了基于WGM谐振腔的光学生化传感器的传感原理、结构和传感应用，重点介绍了其传感特性和优缺点。最后，对基于WGM谐振器的光学生化传感器存在的问题和未来的发展趋势进行了讨论。
Whispering gallery mode (WGM) resonators have attracted extensive attention and their unique characteristics have led to some remarkable achievements. In particular, when combined with optical sensing technology, the WGM reonator-based sensor offers the advantages of small size, high sensitivity and a real-time dynamic response. At present, this type of sensor is widely applied in the bio-chemical sensing field. In this paper, we briefly review the sensing principle, the structures and the sensing applications of optical bio-chemical sensors based on the WGM resonator, with particular focuses on their sensing properties and their advantages and disadvantages. In addition, the existing problems and future development trends of WGM resonator-based optical bio-chemical sensors are discussed.
