Development of a combined surface plasmon resonance/surface acoustic wave device for the characterization of biomolecules [PDF]

open access: yes, 2009
It is known that acoustic sensor devices, if operated in liquid phase, are sensitive not just to the mass of the analyte but also to various other parameters, such as size, shape, charge and elastic constants of the analyte as well as bound and viscously

Mechanism and kinetics of uric acid adsorption on nanosized hydroxyapatite coating

open access: yesJournal of Saudi Chemical Society, 2019
Uric acid (UA) produced from purine metabolism is rather harmful to human health when its concentration is high. To better understand the application of hydroxyapatite (HAP) as an adsorbent for UA removal, quartz crystal microbalance (QCM) technique was ...

Molecularly Imprinted Quartz Crystal Microbalance Sensor (QCM) for Bilirubin Detection [PDF]

open access: yesChemosensors, 2016
This study aims the preparation of a QCM sensor for the detection of bilirubin in human plasma. Bilirubin-imprinted poly-(2-hydroxyethyl methacrylate-N-methacryloyl-l-tryptophan methyl ester) (PHEMATrp) nanofilm (MIP) on the gold surface of a QCM chip was synthesized by the molecular imprinting technique.

BVD model for QCM loaded by viscoelastic film in gas phase application

open access: yesAIP Advances, 2020
As an ultra-sensitivity sensor, a quartz crystal microbalance (QCM) could be used to quantitatively characterize the relation between QCM parameters and the characteristics of viscoelastic films.

Photo-induced changes in the Langmuir adsorption constants of metal oxide layers in self-cleaning cation sensors. [PDF]

open access: yes, 2012
For the first time, we have used a metal oxide-coated quartz crystal microbalance (QCM) to measure Cs+ adsorption onto illuminated and un-illuminated mesoporous TiO2 (m-TiO2) films by microgravimetric means in-situ. In the simplest case, such experiments

A study of quartz crystal microbalance modified with polyvinyl acetate nanofiber to differentiate short-chain alcohol isomers

open access: yesSensing and Bio-Sensing Research, 2019
The detection of short-chain alcohols and their isomers in the atmosphere remains a challenge in solving environmental, occupational safety, and health issues. We report on the sensing of isomers of butanol by quartz crystal microbalance (QCM). QCM chips
