Inwardly grafted polymer brushes is spherical capsules

What is it about?

The structure and scaling properties of inwardly curved polymer brushes, tethered under good solvent conditions to the inner surface of spherical shells like membranes and vesicles with radius R, are studied by extensive Molecular Dynamics simulations and compared with earlier theoretical predictions for different molecular weight of the polymer chains N and grafting density σ g in the case of strong surface curvature, 1/R .

Why is it important?

Recent scientific interest has been focused on brushes on curved (most convex) interfaces in view of their wide scale applications in drug delivery, oil recovery, emulsion stabilization , superhydrophobic coatings, etc. whereas the properties of such coatings in spherical capsules as vesicles and spherical lipid membranes are still insufficiently explored and understood.
