What to consider when analyzing combined QCM-D and ellipsometry data

QCM-D and ellipsometry are two surface sensitive real-time technologies that can be used in combination to give synergistic effects. To make to most of the combined output data, there are some aspects to consider when setting up the combined experiment and when analyzing the captured data.

Why measure dynamic contact angles?

Contact angles are routinely measured as they offer simple, yet extremely sensitive measurement method for surface characterization. Although, the static contact angle is an excellent tool, more in-depth understanding of the surface properties require dynamic contact angle measurements.

What is the difference between QCM mass and Ellipsometry mass?

The mass extracted by QCM-D and ellipsometry are often not the same. So, what is the difference between these masses, and why are they not equal?

How to make better blood-repellent surfaces?

Blood-repellent surfaces are needed in medical devices that come in contact with blood. The traditional approach has been the use of antithrombotic surface treatments However, these coatings are prone to eventually wear-off. Superhydrophobic surfaces have been proposed as an alternative solution.

What is the Sauerbrey equation?

In the context of QCM technology, there is often a reference to the so-called Sauerbrey equation. Here we explain what this equation is, and when it should be used.
