Measurement Science and Technology, 2008
The Sauerbrey equation, widely used in quartz crystal microbalances (QCM), expresses the relationship between resonance frequency changes and mass load changes. When a QCM is used in a liquid, however, its resonance frequency is known to be affected not just by the mass load but also by the viscous load of the liquid.

Detection of triazophos using quartz crystal microbalance (QCM) immunosensor
2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008Quartz crystal microbalance (QCM) immunosensors are based on the principle that adsorption of substances on the surface of a quartz crystal changes its resonance oscillation frequency. A QCM immunosensor was developed for the detection of triazophos by pre-coating the QCMs with toxin-specific antibodies.

Affinity Measurements of Biological Molecules by a Quartz Crystal Microbalance (QCM) Biosensor
2004We present a immunosensing system based on a quartz crystal microbalance (QCM) that allows detection and evaluation of a broad range of molecules relevant to medicine and biology. Soluble analyte is applied by injection into a flow-through chamber where receptor molecules are immobilized, thus enabling real-time measurement of the specific ...

Monitoring the Cellular Binding Events with Quartz Crystal Microbalance (QCM) Biosensors
2017Quartz crystal microbalance (QCM) biosensors have been demonstrated as noninvasive and label-free tools for cell based measurements. However, the complexity of biofilms composed of cells with the associated liquid environments is preventive towards forming explicit relationship between the added mass and the change in the frequency output signal ...

Film formation of ω-aminoalkylcellulose carbamates – A quartz crystal microbalance (QCM) study
Carbohydrate Polymers, 2015The film formation of novel ω-aminoalkylcellulose carbamates on gold surface was studied by means of quartz crystal microbalance with dissipation monitoring (QCM-D) and atomic force microscopy (AFM). The influence of the pH value of the buffer solution, the concentration, the degree of polymerization, and the structure (spacer length) of the polymers ...

Development of a Biological Protocol for Endotoxin Detection Using Quartz Crystal Microbalance (QCM)
Applied Biochemistry and Biotechnology, 2014In this paper, a biological protocol for endotoxin detection has been developed and optimized by quartz crystal microbalance (QCM). The parameters involved in the formation of the self-assembled monolayer (SAM) have been analyzed, and a study of the pH of the ligand buffer has been performed in order to find the best condition for the ligand ...

Detection of two orchid viruses using quartz crystal microbalance (QCM) immunosensors
Journal of Virological Methods, 2002Quartz crystal microbalance (QCM) immunosensors are based on the principle that adsorption of substances on the surface of a quartz crystal changes its resonance oscillation frequency. A QCM immunosensor was developed for the detection of both cymbidium mosaic potexvirus (CymMV) and odontoglossum ringspot tobamovirus (ORSV) by pre-coating the QCMs with

Development of a QCM (Quartz Crystal Microbalance) Biosensor to Detection of Mycotoxins
2013In this study, we have used a direct immunoassay where the simple binding between antigen and an antibody is detected. Immunoassays were performed in a drop system, monitoring the decrease in the frequency of the quartz crystal microbalance device as the mass increases during immunoreaction.
