Anisotropic multicompartment micro- and nano-capsules produced via embedding into biocompatible PLL/HA films

We present a novel strategy to fabricate anisotropic multi-compartment Janus capsules by embedding larger containers into a soft poly-L-lysine/hyaluronic acid (PLL/HA) polymeric film, followed by adsorption of smaller containers on top of their unmasked surface. This research is also attractive for developing substrates for cell cultures.
