Monodisperse stimuli-responsive hydrogel cap-sules were synthesized in the 100 nm - 10 �m diameter range from poly(4-vinylpyridine) and polyethyleneimine using a simple and efficient cross-linking-precipitation template method in conditions of good solvent. The capsules demonstrate that pH-and ionic-strength triggered swelling/shrinking results in size-selective uptake and release properties.
