Abstract

The polymerization of norepinephrine, and the properties of the related polymer polynorepinephrine, started to be investigated barely 9 years ago and only few works were produced so far, mainly in materials science and medicine. An unexpectedly low relevance, especially if compared with the interest toward dopamine and polydopamine, differing from norepinephrine only for a hydroxyl group and whose properties were deeply investigated and applied to an impressive number of subject areas. We show here that in some cases, norepinephrine and dopamine monomers can be exchanged without virtually affecting the experimental results. But even more interesting, the choice of norepinephrine can positively influence the properties of the final polymer. In particular, the smoother and more hydrophilic surface of polynorepinephrine may enhance cell adhesion and proliferation, increase the activity of conjugated biomolecules, and induce higher cellular uptake of nanodrugs. Moreover, polynorepinephrine presents an additional anchoring point that can be exploited for further functionalization. Nevertheless, despite its potential for bioconjugation and molecular recognition, polynorepinephrine has not yet been considered in biosensing. Here we report our feelings in terms of perspective use of polynorepinephrine as new functional monomer for biomimetic receptor development by molecular imprinting, with application in affinity biosensing.
