Outcomes can be shaped where materials meet
Across products and processes, whether things work as intended or fail can depend on what happens at surfaces and interfaces.
A cleaning step may remove a soil layer or leave residues behind. A membrane may keep its flow — or foul and lose performance. A formulation may remain stable — or interact with a surface in ways that cause loss or incompatibility. A battery may remain safe and long-lived — or degrade through unstable interfaces and dendrite growth.
In each case, the visible outcome can depend on dynamic interfacial processes that are not always apparent from conventional bulk, endpoint or before-and-after measurements.

At surfaces and interfaces, molecules, particles and films can adsorb, desorb, bind, release, build up, degrade, swell, collapse, foul, reorganize or be removed.
These processes may be small in scale, but they can have a large effect on the outcomes you care about: stability, fouling, cleaning efficiency, material compatibility, biocompatibility, battery lifetime, process efficiency and more.
When interfacial processes go unnoticed, you may see the outcome without understanding the cause. To design and improve these systems, you need insight into what happens at surfaces and interfaces as the process unfolds.

"QCM-D technology is a key part of our biointerfacial science research that spans fundamental biomacromolecular investigations to applied studies involving antiviral drug development. The QSense instruments, which we have used for nearly two decades, are robust and can track complex biological phenomena in real-time and with label-free readouts that have helped us to deeply characterize a wide range of systems related to proteins and lipid membranes. Together with our analytical modeling efforts, there is a really bright future to continue applying QCM-D technology in new directions across many important scientific disciplines."
"Using QSense measurement tools, our lab has investigated many very interesting protein and lipid systems in aqueous and non-aqueous environments and the QCM-D measurement capabilities have proven critical to study molecular-level interaction behaviors at solid-liquid interfaces. One of the most exciting examples has involved antimicrobial lipids, in which case the QCM-D technique has proven extremely useful to distinguish the mechanisms of action of different compounds interacting with membrane-mimicking supported lipid bilayers. Such mechanistic distinctions were seen for the first time by the QCM-D technique, demonstrating its potential to complement and in some cases surpass the analytical capabilities of traditional biological assays. Looking forward, we see enormous potential to translate fundamental insights obtained from QCM-D measurements into numerous applications across the healthcare, biotechnology, and agricultural spaces among various opportunities."
