The dopamine/PEI film with controlled amine density was successfully prepared.
The DNA aptamer was assembled onto the film via electrostatic incorporation.

The A@DP film can support the survival of ECs, control the hyperplasia of SMCs.
The dynamic/co-culture models are useful for studying cells competitive adhesion.
