One-chip multichannel quartz crystal microbalance (QCM) fabricated by Deep RIE

Sensors and Actuators A: Physical, 2000
Abstract In this paper, we present a one-chip multichannel quartz crystal microbalance (QCM) sensor fabricated by deep reactive ion etching (Deep RIE). An inductively coupled plasma reactive ion etching (ICP RIE) using SF 6 gas has been applied to the Deep RIE of quartz.

The Quartz Crystal Microbalance (QCM) as an lmmunosensor

2003
This chapter demonstrates a preliminary experimental approach to detect antiviral antibodies by means of a quartz crystal immunosensor. As an example of the large numbers of immunoassays currently applied in the clinical laboratory, the screening for human immunodeficiency virus (HIV) specific antibodies was presented as a model application. The quartz

Detection of triazophos using quartz crystal microbalance (QCM) immunosensor

2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008
Quartz 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.

Dissipation in Films of Adsorbed Nanospheres Studied by Quartz Crystal Microbalance (QCM)

Analytical Chemistry, 2009
The quartz crystal microbalance (QCM) has become a popular method to study the formation of surface-confined films that consist of discrete biomolecular objects--such as proteins, phospholipid vesicles, virus particles--in liquids. The quantitative interpretation of QCM data--frequency and bandwidth (or, equivalently, dissipation) shifts--obtained with

Humidity Sensor Based on Polymer Coated Quartz Crystal Microbalance (QCM)

First International Conference on Integration and Commercialization of Micro and Nanosystems, Parts A and B, 2007
Humidity sensors featured by the combination of a quartz crystal microbalance (QCM) and polyvinylpyrrolidone (PVP) film were fabricated. PVP films were distributed onto the electrode surfaces of quartz crystal by drop-coating. The electrical characteristics of the devices as a function of relative humidity (RH %) measured in the airtight testing ...

Film formation of ω-aminoalkylcellulose carbamates – A quartz crystal microbalance (QCM) study

Carbohydrate Polymers, 2015
The 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 ...

Monitoring the Cellular Binding Events with Quartz Crystal Microbalance (QCM) Biosensors

2017
Quartz 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 ...

Affinity Measurements of Biological Molecules by a Quartz Crystal Microbalance (QCM) Biosensor

2004
We 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 ...

Development of a Biological Protocol for Endotoxin Detection Using Quartz Crystal Microbalance (QCM)

Applied Biochemistry and Biotechnology, 2014
In 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 ...
