| Abstract | Whispering gallery mode (WGM) microtubule resonators are widely used in highly sensitive sensing applications due to their ultra-high quality factor Q and extremely small mode size. Capillary microtubules, as sensing devices, have the advantages of low reagent sample consumption, a large specifi c surface area to enhance analytical sensitivity, and a fast mass transfer rate to shorten analysis time. In recent years, research scholars have conducted extensive and in-depth studies on the optimization of microtubule resonators. However, there are still several problems that limit the development of the technology applications and solutions that need to be explored. Therefore, this paper analyzes the current research status of resonant sensing technology in microtubule whispering gallery, analyzes key problems, and points out research priorities and methods in coupled resonance technology and microtubule structure optimization. Finally, suggestions for future development are made. Capillary microcavity Whispering gallery mode (WGM) resonators with high Q and small mode volume are well suited for applications in high sensitivity sensing. Such as biosensing, temperature sensing, pressure sensing, fl ow rate sensing, strain sensing, and magnetic sensing, etc. The article analyzes the key technologies of capillary microcavity WGM resonant sens- ing, focusing on the coupled resonant technology to excite capillary WGM, capillary structure parameter optimization and sensor packaging, and provides an outlook on the future development. |
