Rotational mobility in spherical membranes: The interplay between Saffman-Delbrück length and inclusion size
Marco Vona, Eric Lauga
The mobility of particles in fluid membranes is a fundamental aspect of many biological processes. In a 1975 paper [1], Saffman and Delbrück demonstrated how the presence of exter…
