Abstract
<p class="first" id="P1">Polydopamine is one of the simplest and most versatile approaches
to functionalizing
material surfaces, having been inspired by the adhesive nature of catechols and amines
in mussel adhesive proteins. Since its first report in 2007, a decade of studies on
polydopamine molecular structure, deposition conditions, and physicochemical properties
have ensued. During this time, potential uses of polydopamine coatings have expanded
in many unforeseen directions, seemingly only limited by the creativity of researchers
seeking simple solutions to manipulating surface chemistry. In this review, we describe
the current state of the art in polydopamine coating methods, describe efforts underway
to uncover and tailor the complex structure and chemical properties of polydopamine,
and identify emerging trends and needs in polydopamine research, including the use
of dopamine analogs, nitrogen-free polyphenolic precursors, and improvement of coating
mechanical properties.
