研究目的:

由于 CPR 细菌难以独立存活,传统的方法难以分离,本研究拟采用液滴微流控技术,一方面隔离空间,使细菌不受群体群落的影响,另一方面可以得到大量单液滴,有可能分离出更多 CPR 细菌及其宿主。这有助于了解人类口腔中 CPR 细菌与宿主的共生机制,以更好地了解口腔中 CPR 细菌的功能,为临床上的治疗提供思路。  

Objectives of Study:

Because CPR bacteria are hard to survive on their own, traditional methods struggle to isolate them. This study plans to use droplet microfluidics technology, which can isolate them in tiny spaces so they aren't affected by the community around them, and at the same time, produce a lot of single droplets, potentially isolating more CPR bacteria and their hosts. This can help us understand how CPR bacteria coexist with their hosts in the human mouth, better grasp their role in oral health, and provide ideas for clinical treatments.
