摘要：

In our sensing configuration, the quartz crystal microbalance device is employed for the first time for the solid phase amplification via the recombinase polymerase amplification method and simultaneous detection of DNA amplicons on the device surface. For amplicon detection, a novel methodology is described, where the formation of surface-bound DNA amplicons is detected by using liposomes as an amplification probe and by selectively monitoring the dissipation change during liposome binding. The presented methodology possesses several advantages over existing methods, i.e., it is fast, achieving the detection of DNA produced after only 5 min of amplification, and simple, since it does not require any post-Amplification DNA extraction step. © 2017 IEEE.
