Cells constantly experience mechanical forces during growth and development. Increasing evidence suggests that mechanical forces can regulate cellular processes such as proliferation, migration, and differentiation. Therefore, developing new tools to measure and manipulate cellular mechanical forces is essential. DNA nanostructures, due to their simple design and high programmability, have been utilized to create various mechanical sensors and have become a key tool for studying mechanical information in both cellular and non-cellular systems. In this article, we review the development of DNA-based mechanical sensors and their applications in measuring mechanical forces in the extracellular matrix and cell–cell interactions and summarize the latest advances in monitoring and manipulating cellular morphology and function. We hope that this review can provide insights for the development of new mechanical nanodevices.
