MicroVacuum’s QCM 3000 Wet & Dry Mass measuring system includes two biosensor systems in one: An acoustic biosensor (Quartz Crystal Microbalance with Dissipation Monitoring) for “wet” mass measurement with an additional optical biosensor (OWLS) for “dry” mass measurement. There is also an option for synchronized electrochemical setup for the QCM 3000 system. For references, pricing […]
Introducing QCM-I Net, MicroVacuum’s new solution for multi-channel QCM-D measurements with unlimited options
We are very excited to announce the availability of our new QCM-I NetTM multi-channel QCM-D solution. MicroVacuum’s QCM devices have long been market leading instruments for Quartz Crystal Microbalance measurements with impedance (QCM-I) and dissipation monitoring (QCM-D). Modularity and affordability were always one of our differentiators compared to other companies’ offerings, without ever compromising on […]
QCM-I is a powerful technique for measuring the adsorption or binding of polymers, proteins, nano-particles and other molecules to a surface. Multi-parametric data is obtained in real time, detailing changes of the hydrated mass and rigidity of layers coupled to the sensor surface. Here, the mass and viscoelastic changes can be understood for a range […]
Understanding the adsorption of surface active layers is complex. The most useful real-time techniques provide multiple pieces of information, however a much clearer picture can be obtained by combining such techniques.1 QCM-I measures changes relating to the hydrated mass and rigidity of surface layers. Combining this with an optical technique such as OWLS, the “dry mass” […]
The QCM-I and QCM-I Mini systems are designed to be modular so that they can be configured to use the sensors and sample environments that are most appropriate for the user’s experiments. This technical note summarizes the basic configurations that can be used with the QCM-I for measuring the effect of changes in humidity on […]
Micron-thick films of Coconut Oil can be formed by spin-coating and the thickness of the solid films estimated using QCM-I. The viscoelastic changes in the layers can be observed during melting and subsequent structural reorganization on re-solidification. This data can be compared to the effect of dish-cleaning detergent on the films at low temperatures in […]
The BioSense 3 software controls and records experiments using the Quartz Crystal Microbalance with Impedance (QCM-I) instrument. Other instrumentation can also be controlled with the software to provide integrated experiments, e.g. Gamry potentiostats for electrochemical QCM-I measurements. Other equipment can also be synchronized with the QCM-I experiment using the digital In/Out port. This technical note […]
The electrostatically driven adsorption of polymer and nano-particle multilayers is a well-established method for the physical and chemical transformation of surfaces to produce highly tailored and often “smart”, environmentally sensitive interfaces. The deposition process can be sensitively monitored using QCM-I, which provides information on the hydrated mass of the multilayer as well as its physical […]
The Quartz Crystal Microbalance in Soft Matter Research: Fundamentals and Modeling (Soft and Biological Matter)
This book describes the physics of the second-generation quartz crystal microbalance (QCM), a fundamental method of analysis for soft matter at interfaces. Available as eTextbook for rent for $26.16 for a month, and also for purchase as paperback and hardcover.
With contributions from experts in the field, the Handbook of Biosensors and Biochips provides an essential reference, underpinning many of the applications used in medical diagnostics, environmental control and pharmaceutical and food industries. It presents an invaluable addition for those in both academia and industry.
