Magnetic Tweezers in a Microplate Format [PDF]
Journal of Visualized Experiments, 2022 Mechanobiology describes how the physical forces and mechanical properties of biological material contribute to physiology and disease. Typically, these approaches are limited single-molecule methods, which restricts their availability. To address this need, a microplate assay was developed that enables mechanical manipulation while performing standard
