青岛能源所单细胞研究中心的研究小组发明了pDEP-RADS技术(如图),并在此关键技术的基础上研制出FlowRACS。研究人员采用低拉曼背景石英玻璃为微流控芯片基材,以提高表型检测的普适性;以氧化铟锡(而非金属)加工电极阵列,以避免光热损伤;采用先拉曼检测后液滴包裹、液滴产生和分选同步进行的策略,避免液滴对拉曼信号采集...
To improve the process, researchers applied positive dielectrophoresis (pDEP), which can capture or mobilize particles. This allows trapping fast-moving single microbial cells, processing them precisely yet rapidly through a Raman detection point to recognize those cells that produce particular enzymes or...
