Quartz Crystal Microbalance (QCM-D)

QSense Analyzer from Biolin Scientific

What Does the QSense Analyzer Measure?

Unlike traditional surface analysis tools, the QSense Analyzer simultaneously measures both:

• Mass changes at the surface (including hydrated mass)
• Viscoelastic properties of thin films and adsorbed layers

This dual capability enables a deeper understanding of how materials interact, not only how much material is present, but also how it behaves structurally.

Key Applications

The QSense Analyzer is widely used across research and industry for studying:

• Biomolecular interactions
  Protein adsorption, ligand–receptor binding, antibody–antigen interactions, and DNA hybridization.
• Surface coatings and thin films
  Characterization of polymers, multilayer assemblies, and functional coatings.
• Cell and bacterial studies
  Cell attachment, spreading, and biofilm formation on surfaces.
• Nanomaterials and soft matter
  Behavior of nanoparticles, vesicles, liposomes, and hydrogels.
• Electrochemistry and corrosion processes
  Monitoring surface changes during electrochemical reactions.
• Food, pharmaceutical, and cosmetic formulations
  Stability and structure of complex formulations at interfaces.

Key Advantages

• Real-time monitoring of dynamic processes
• High sensitivity to nanoscale mass changes
• Simultaneous structural insight through dissipation measurements
• Versatile environmental control, including liquid flow, temperature, and chemical conditions

Why Choose QSense Analyzer?

The QSense Analyzer goes beyond simple mass detection, offering a complete picture of interfacial phenomena. Its ability to capture both quantitative and structural information makes it an essential tool for researchers and engineers working with complex surface processes.
