Beschreibung
Zusammenfassung:	A diagnostic system for determining the presence of a target in a sample liquid includes a diagnostic reader and a microfluidic strip having a network of microfluidic channels therein. An actuator within the reader varies the pressure of a gas in gas communication with the liquid-gas interface of the sample liquid within the microfluidic channel network to move and/or mix the sample liquid. The pressure change may be continuous and/or oscillating. 用于确定样品液体中目标的存在的诊断系统，包括诊断读取器和其中具有微流体通道网络的微流体条带。读取器内的致动器改变与微流体通道网络内的样品液体的液-气界面气体连通的气体的压力以移动和/或混合样品液体。压力改变可以是连续的和/或振荡的。
