Adsorption on Ligand-Tethered Nanoparticles
M Borowko and T Staszewski, INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES, 22, 8810 (2021).
We use coarse-grained molecular dynamics simulations to study adsorption on ligand-tethered particles. Nanoparticles with attached flexible and stiff ligands are considered. We discuss how the excess adsorption isotherm, the thickness of the polymer corona, and its morphology depend on the number of ligands, their length, the size of the core, and the interaction parameters. We investigate the adsorption-induced structural transitions of polymer coatings. The behavior of systems involving curved and flat "brushes" is compared.
