Malkiat Johal on QSense
"I have found QSense to be one of the best techniques for an undergraduate lab because it’s turnkey and it requires very little maintenance."
![Johal Malkiat-1](https://www.biolinscientific.com/hs-fs/hubfs/Johal%20Malkiat-1.png?width=600&name=Johal%20Malkiat-1.png)
Malkiat Johal, Professor of Chemistry, Pomona College
"The operating principles are straightforward and the students can focus on the science. And so, that’s something that we have been really happy with, it really works in this kind of setting. It’s an ideal method for an undergraduate surface science lab."
Jodie Lutkenhaus on QSense
"We can monitor the mass change of our system in real-time. I can tell you that for every electron moved, this amount of mass changed. That’s powerful. You can’t really get that with any other system."
![Jodie Lutkenhaus](https://www.biolinscientific.com/hs-fs/hubfs/Jodie%20Lutkenhaus.png?width=600&name=Jodie%20Lutkenhaus.png)
Jodie Lutkenhaus, Associate Professor, Texas A&M University
"We use the QSense high temperature model that allows us to investigate polyelectrolyte complexes and their response to temperature. We’re also using the electrochemistry module so we can run our standard electrochemical measurements at the same time as we run the QCM-D."
Kenichi Sakai on QSense
"We regard QCM-D as a valuable measuring tool due to its high sensitivity and stability and find it applicable for versatile studies because of its availabilities of sensors with different types of surfaces. In this context I would say QCM-D is the best suitable solution for simulating a variety of nanoscale interaction behaviors both real-time & in-situ.
![Kenichi-Sakai](https://www.biolinscientific.com/hs-fs/hubfs/Kenichi-Sakai.png?width=600&name=Kenichi-Sakai.png)
Kenichi Sakai, Associate Professor, Tokyo University of Science
"We are working on academic research in the field of colloid and interface chemistry and our main work is synthesis of novel surfactants and characterization of their properties. We use QCM-D as a must-tool to comprehend molecular adsorption/desorption behaviors specifically observed at a solid-liquid interface."
Marité Cárdenas on QSense
"QSense instruments are a great tool for our biophysical research. They enable rapid screening for biomolecular interaction at lipid bilayers and also allow optimising the parameters for deposition of thin films."

Professor Dr. Marité Cárdenas, Health and Society, Malmö University
"The instrument is easy to use, and has a long working life as long as you follow the maintenance instructions! The technical staff at Biolin Scientific are a pleasure to work with: They are nice and always give quick feedback and support."
