Special Issue Information

Dear Colleagues,

Recent advances in nanoscience and nanotechnology have proven their potential to contribute enabling sustainable and novel solutions for energy, biomedicine and the environment. By covering topics from advanced nanomaterials and nanobiomedicine, this Special Issue aims to provide a forum and survey for the current status and future perspectives of this rapidly emerging field.

This Special Issue is cooperating with the NanoTech Poland 2018 conference and the 1st Symposium on Polydopamine (http://nanotechpoland.amu.edu.pl/). Registered participants of this conference are invited to submit their manuscripts to be considered for publication. Authors may consider to contribute an original research article or review in areas related to the conference themes.

Despite extensive investigations over the past decade, the chemical basis of the extraordinary underwater adhesion properties of polydopamine (PDA) has remained not entirely understood. The bulk of evidence points to PDA wet adhesion as a complex process based on film deposition, and growth in which primary amine groups, besides catechol moieties, play a central role. However, the detailed interplay of chemical interactions underlying the dynamics of film formation has not yet been elucidated. Herein, we report the results of a series of experiments showing that coating formation from dopamine at pH 9.0 in carbonate buffer: (a) Requires high dopamine concentrations (>1 mM); (b) is due to species produced in the early stages of dopamine autoxidation; (c) is accelerated by equimolar amounts of periodate causing fast conversion to the o-quinone; and (d) is enhanced by the addition of hexamethylenediamine (HMDA) and other long chain aliphatic amines even at low dopamine concentrations (<1 mM). It is proposed that concentration-dependent PDA film formation reflects the competition between intermolecular amine-quinone condensation processes, leading to adhesive cross-linked oligomer structures, and the intramolecular cyclization route forming little adhesive 5,6-dihydroxyindole (DHI) units. Film growth would then be sustained by dopamine and other soluble species that can be adsorbed on the surface. Full article
