TUM Researchers Measure DNA Base Pair Forces for Molecular Machine Development
Scientists at the Technical University of Munich have successfully measured stacking forces between DNA base pairs at the single-pair level. This breakthrough could enhance the construction of DNA-based molecular machines and improve understanding of biological processes like DNA replication.

Researchers from the Technical University of Munich (TUM) have measured stacking forces between DNA base pairs, a first at the single-pair level. This measurement, involving forces in the range of piconewtons, was achieved using a specialized experimental setup developed over six years in collaboration with various TUM departments.
The findings could significantly impact DNA machine development, with the lab currently constructing a molecular rotational motor that utilizes stacking forces for controlled motion. Understanding these forces may also inform biological processes, such as DNA replication, where short-lived interactions allow for efficient separation of base pairs.
