Quartz crystal microbalance for bacteria application review

This paper presents an overview of the quartz crystal microbalance sensor (QCM) for bacteria application. The QCM sensor can be considered as a representative mechanical transducer for a biosensor device that converts the mass of target analytes into an electrical signal. Microorganisms´ detection using QCM sensor can be applied in applications in the field of environment, biomedical area, and food industry. This paper focuses on the characteristic of QCM as biosensor in the detection of bacteria pathogen. The paper provides a description of the techniques used for QCM when being utilized for bacteria testing. The techniques focus on surface modification of quartz crystal in developing sensitive and selective sensor using Self-assemble Monolayer (SAM) method which cooperates with antigen-antibody principle.
