2D square arrays of protein nanocages through channel-directed electrostatic interactions with poly(α, l-lysine).
Reconstructed ferritin nanocages with expanded 4-fold channels can self-assemble into 2D square arrays through channel-directed electrostatic interactions with poly(α, l-lysine) at pH 7.0. Structurally, protein cages are aligned along their common 4-fold symmetry axis, imposing a fixed disposition of neighboring ferritins.
