 Saffman–Delbrück model

The Saffman–Delbrück model is a theoretical framework used in biophysics and cellular biology to describe the behavior of large biomolecules, such as proteins and membrane receptors, that are embedded in or associated with biological membranes. Specifically, it addresses the motion of these large entities in a viscous fluid, considering both the properties of the biomolecule and the environment of the membrane in which they are located.
