We are very happy to announce that Matt’s review paper “How sticky? How Tight? How Hot? Imaging probes for fluid viscosity, membrane tension and temperature measurements at the cellular level” is published in The International Journal of Biochemistry & Cell Biology. In the paper we review the progress made in imaging probes for three important physical parameters: viscosity, membrane tension, and temperature, all of which play important roles in many cellular processes. We discuss the techniques implementing imaging-based probes to measure viscosity, membrane tension, and temperature at subcellular resolution dynamically. The merits and shortcomings of each technique are examined, and the future applications of the recently developed techniques are also explored. We thank Dr. Tony Kanchanawong’s invitation for this opportunity to write a review paper on this underexplored topic. Congratulations to Matt, the leading author and our wonderful second author/illustrator at large Abdulla!
