BioNavis introduces its new range of Quartz Crystal Microbalance with Dissipation (QCMD) instruments, designed for precision measurements of molecule-surface interactions. These instruments measure key parameters such as viscoelasticity and bound mass, complementing the BioNavis MP-SPR suite for real-time, label-free analysis. With high-frequency sensors, BioNavis QCMD enables sensitive and accurate measurements, providing reliable data for a variety of research applications.
QCMD technology is versatile, and suitable for studying biomolecular interactions, material science, biophysics, biosensor development, and electrochemistry. Researchers can monitor small changes in mass, thickness, and mechanical properties in real-time, without the need for labels. The system’s user-friendly interface, QuickLock cells, and intuitive software make the process straightforward and efficient.
QCMD works by using quartz crystal sensors that oscillate at a specific frequency when an electric voltage is applied. As molecules or films are deposited on the sensor, changes in mass, density, and viscoelastic properties occur, causing shifts in both resonant frequency and dissipation. These shifts allow researchers to gather information about adsorbed layers, such as mass and thickness.
The BioNavis QCMD system offers several advantages, including real-time monitoring, compatibility with both gas and liquid environments, and the ability to measure in complex media like milk and seawater. It can also operate in high-temperature and high-pressure conditions, broadening its range of applications. Additionally, the system can be combined with electrochemistry using a dedicated cell, adding further functionality.
With its accurate measurements and ease of use, BioNavis QCMD technology is well-suited for various research fields, including surface chemistry, biotechnology, and materials science.
