K.H. Roh, D.C. Martin, J. Lahann. Biphasic Janus particles with nanoscale
anisotropy. Nature Materials (2005) 4, 759-763.

Anisotropic material distribution can be induced at the nanometer scale by the use of electrified jetting. Side-by-side dual capillaries were employed to expose two distinct parallel polymer solutions to an electrical field simultaneously. The individual phases of the resulting polymer-based Janus particles can be independently loaded with biomolecules or selectively modified with reactive ligands.

The synthesis of a reactive polymer, poly(4-formyl-p-xylylene-co-p-xylylene), via chemical vapor deposition (CVD) polymerization is reported. Moreover, usefulness of these polymer coatings for biomimetic surface modifications is demonstrated.
