Quartz Crystal Microbalance (QCM) sensor arrays selection for olive oil sensory evaluation

Food Chemistry, 2011
The potential of eight Quartz Crystal Microbalance (QCM) sensor arrays to differentiate the quality of olive oil samples, based on their aromatic profiles, were investigated. Five gas chromatographic stationary phases (OV-17, OV-275, PEG, Span 80 and Vaseline) were used as sensing films of QCM sensors.

Measurement of Molecular Contamination for Satellites Using a Quartz Crystal Microbalance (QCM)

Journal of the IEST, 2004
Quartz Crystal Microbalances (QCMs) have been used to measure the molecular contamination for satellites in vacuum bake-out tests at the Korea Aerospace Research Institute (KARI). Through measurement using QCMs, the mass and the mass deposition rate of molecular contamination could be traced in real-time.

Rapid detection of bacterial spores using a quartz crystal microbalance (QCM) immunoassay

IEEE Sensors Journal, 2005
Weaponized spores of a pathogenic bacterium such as Bacillus anthracis are a new critical threat to mankind. The occurrences in New York and south Florida in 2001 showed the potential capability of the spores to be used for mass destruction. Due to their stealthiness during the infection and resistance to harsh environment, an early and prompt ...

Quartz Crystal Microbalance - QCM

2009
The Quartz Crystal Microbalance (QCM) technique determines mass density and viscoelastic properties of a system in contact with a quartz sensor by measuring the characteristic impedance of the acoustic resonator. The measured quantities are either the complete impedance structure or the resonance frequency and a parameter associated with damping, e.g ...

Quartz-Crystal Microbalance (QCM) for Public Health: An Overview of Its Applications.

Advances in protein chemistry and structural biology, 2015
Nanobiotechnologies, from the convergence of nanotechnology and molecular biology and postgenomics medicine, play a major role in the field of public health. This overview summarizes the potentiality of piezoelectric sensors, and in particular, of quartz-crystal microbalance (QCM), a physical nanogram-sensitive device. QCM enables the rapid, real time,

Development of a QCM (Quartz Crystal Microbalance) biosensor to detection of mycotoxins

2014
In 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.

Affinity Measurements of Antibody Fragments on Phage by Quartz Crystal Microbalance (QCM)

2001
U The screening of large combinatorial phage display gene libraries usually leads to a set of diverse recombinant antibody fragment clones specifically binding to the antigen which have to be characterised further and ranked for their usefulness. Beside specificity, the key parameter to be determined is the affinity to the antigen.
