Abstract

Studies of spherical nanoengineered drug delivery systems have suggested that particle size and mechanical properties are key determinants of in vivo behavior; however, for more complex structures, detailed analysis of correlations between in vitro characterization and in vivo disposition is lacking. Anisotropic materials in particular bear unknowns in terms of size tolerances for in vivo clearance and the impact of shape and rigidity. Herein, we employed cylindrical polymer brushes (CPBs) to answer questions related to the impact of size, length and rigidity on the in vivo behavior of PEGylated anisotropic structures, in particular their pharmacokinetics and biodistribution. The modular gra..
