Development of flowing automatic quartz crystal microbalance system for DNA detection.

A novel flowing automatic QCM (Quartz Crystal Microbalance) system for DNA detection was fabricated in this paper. The system included a multi-channel flowing system, a flow cell and a constant temperature controlling system, which integrated multi-functions such as flowing detection, temperature controlling and automatic analysis. Moreover, this system was utilized for DNA immobilization and hybridization detection. The results showed that the system is of good stability and validity.
