Nanoscale Analysis of Surface Interactions and Reactions

Q-Sense Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D) systems enable a wide range of industrial applications as well as cutting edge academic research. QCM-D is a real-time, label-free technique with nanogram sensitivity that enables analysis of the following:

  • Mass changes and interactions occurring at surfaces
  • Changes in rigidity and softness of surface bound materials

Phenomena that can be measured include:

  • Interactions, reactions and other surface phenomena
  • Cross-linking and aggregation
  • Thin film swelling, dissolution and corrosion

Analytes that can be analyzed include:

  • Polymers
  • Surfactants
  • Proteins
  • Nanoparticles
  • Lipids
  • Cells
  • Petroleum components
  • Nanocomposite materials

QCM-D can also be combined with other methods, including electrochemistry, ellipsometry and microscopy.
