Explore advanced scanning probe microscopy techniques for characterizing the mechanical properties of biomolecular condensates in this 22-minute conference lecture. Learn how to overcome limitations of traditional rheological methods that are restricted to small forces and struggle with measurements of higher elasticity droplets and solid transitions. Discover the development of novel assays using scanning probe microscopy for comprehensive mechanical characterization of biomolecular condensates, demonstrated through studies of heterotypic poly-L-lysine heparin condensates. Examine the multi-route transition from liquid-like to gel states and understand how chemical alterations of the medium can rejuvenate these condensates. Gain insights into the advantages of probe-based methods, including rapid, high-throughput capabilities, high-force range studies, and integration with nanoscale morphological measurements. Understand how these advances contribute to accelerated development of therapies by enhancing our comprehension of condensate behavior and dynamics in biological systems.
