Application of a flow type quartz crystal microbalance immunosensor for real time determination of cattle bovine ephemeral fever virus in liquid.

Bovine ephemeral fever (BEF) is a viral disease of cattle. A flow type quartz crystal microbalance (QCM) immunosensor was developed for the real time determination BEF virus (BEFV) that is suitable for clinical point-case diagnosis. Self-assembled monolayer (SAM) of thiols and sulphides by the cystamine-glutaraldehyde method was used for the immobilization of BEFV monoclonal antibody on the gold surface of a quartz crystal microbalance (QCM).

Series quartz crystal sensor for remote bacteria population monitoring in raw milk via the Internet.

A remote monitoring system based on a piezoelectric quartz crystal (SPQC) sensor was developed for the determination of the bacteria population in raw milk. The system employs the Windows XP server operating system, and its programs for data acquisition, display and transmission were developed using the LabVIEW 7.1 programming language.
