The Dynamic Response (DR) is a parameter that characterizes the switching speed of DNA nanolevers. It is automatically calculated from the raw data by the switchSENSE® software package. For every recorded data point, the software evaluates typically the upward motion...
The hydrodynamic diameter (Dh) of a molecule is defined as the diameter of a perfect solid sphere that would exhibit the same hydrodynamic friction as the molecule of interest. Thus, the Dh value reflects primarily the hydrodynamic friction but is usually also a good...
The so-called lollipop model is a biophysical model, which allows to simulate the behavior of end-tethered DNA-nanolevers on chargeable surfaces. It mathematically simplifies the hydrodynamic properties of DNA nanolevers with attached protein molecules by assuming...
Molecular Dynamics Hydrodynamic changes can be detected as changes in the Dynamic Response. Generally, events that increase the hydrodynamic friction, such as binding of an analyte molecule to the ligand, result in a slower switching motion, which can be observed as a...
