Polydopamine (PDA) is a useful bio-inspired coating for surface modification. Substrates from noble metals such as gold to semiconductors such as silicon can be modified to exhibit useful biomimetic properties that may not be available on the underlying surface. However, conditions of preparation can lead to wide variability in the attributes (such as roughness) of the generated surface, and can affect subsequent functionalization and applicability. Wider adoption of the routine use of PDA is hindered by this uncertainty of the nature of the prepared surface. We present strategies for greater control of the properties of a PDA coating, which could lead to enhanced predictability of surface attributes and greater utility in surface engineering strategies.
