Described is application of the remote-query (wireless, passive) magnetoelastic sensor platform for direct detection and monitoring of bacterium contamination of milk within hermetically sealed containers. Specific application is made to the quantification of Staphylococcus aureus ssp. anaerobius (S. aureus) concentrations in milk. S. aureus growth changes milk viscosity, in turn changing the resonance frequency of the liquid immersed sensor allowing S. aureus concentrations of 10(3) to 10(7)cellsml(-1) to be directly quantified.
描述了远程查询（无线、无源）磁弹性传感器平台在直接检测和监测密封容器内牛奶细菌污染方面的应用。具体应用于定量牛奶中金黄色葡萄球菌厌氧亚种（金黄色葡萄球菌）的浓度。金黄色葡萄球菌的生长会改变牛奶的粘度，进而改变浸入液体的传感器的共振频率，从而可以直接定量10³至10⁷个细胞/毫升的金黄色葡萄球菌浓度。
