WebJan 17, 2024 · A number of force-based micromanipulation technologies have been developed to study the mechanics of DNA at the single-molecule level [ 1, 2 ]. These include optical tweezers (OTs), magnetic tweezers (MTs) and atomic force microscopy (AFM). Molecular-level elasticity studies of single DNA tethers are now performed routinely … Tethered particle motion (TPM) is a biophysical method that is used for studying various polymers such as DNA and their interaction with other entities such as proteins. The method allows observers to measure various physical properties on the substances, as well as to measure the properties of biochemical interactions …
