Dear colleagues,
If you are working on biosensors—and many of you are—you will already be familiar with a variety of transducers established using, for example, optical, electronic, electrochemical, and microgravimetric techniques. In this webinar, we will introduce the principle of thermal biosensors, produced, for example, using the heat-transfer method (HTM), which employs temperature gradients and thermal currents to probe biomolecular interactions. In principle, the concept is rather simple: you need a heat source and two thermometers, and you are ready to detect, for example, bacteria, virus particles, or mutations in DNA. Of course, this does not work without bioreceptors, but when a suitable receptor is included, the HTM becomes sensitive to an incredibly broad range of biotargets. There are also receptor-free HTM applications, such as monitoring cell proliferation and evaluating the efficacy of antimicrobials at the cell culture level.
We are grateful to MDPI for organizing this webinar, and a special thanks goes to today’s three speakers: they not only pioneered the basic HTM principle but also continue to advance it toward real-life applications in medical diagnostics, food safety, and environmental monitoring.
I wish you all a pleasant and fruitful webinar.
Best regards,
Patrick Wagner, KU Leuven

This webinar on “Thermal Biosensing Methods” provided a comprehensive overview on techniques that are based on interface thermal resistance and thermal effusivity, unlike calorimetric biosensors. These techniques are novel in a biosensing context and cover a surprisingly wide application range, including the detection of DNA mutations, virus particles and disease biomarkers in body fluids and monitoring cell proliferation and metabolic heat. While thermal methods are robust and powerful, they only require minimum instrumentation and can be easily combined with other transducers to obtain multiparametric information. Not in the least, thermal biosensors are always valuable for generating new insights and unexpected discoveries—stay tuned!
