Development of a polystyrene sulfonate/silver nanocomposite with self-healing properties for biomaterial applications

Girard, Jérôme ; Brunetto, Priscilla S. ; Braissant, Olivier ; Rajacic, Zarko ; Khanna, Nina ; Landmann, Regine ; Daniels, Alma U. ; Fromm, Katharina M.

A silver polystyrene sulfonate polyelectrolyte was synthesized, showing a spontaneous reduction of silver ions to silver nanoparticles over a period of approximately 1 month. A follow-up of the nanoparticle formation via scanning electron microscopy (SEM) reveals migration of the nanoparticles towards the cracks of the polymer over time, leading to a self-healing process of the nanocomposite....

Of chains and rings: synthetic strategies and theoretical investigations for tuning the structure of silver coordination compounds and their applications

Slenters, Tünde Vig ; Sagué, Jorge L. ; Brunetto, Priscilla S. ; Zuber, Stefanie ; Fleury, Antoine ; Mirolo, Laurent ; Robin, Adeline Y. ; Meuwly, Markus ; Gordon, Oliver ; Landmann, Regine ; Daniels, Alma U. ; Fromm, Katharina M.

In: Materials, 2010, vol. 3, no. 5, p. 3407-3429

Varying the polyethyleneglycol spacer between two (iso)-nicotinic groups of the ligand systems, a large structural variety of silver coordination compounds was obtained, starting with zero-dimensional ring systems, via one-dimensional chains, helices and double-helices to two-dimensional polycatenanes. Theoretical calculations help to understand their formation and allow predictions in some...

Silver coordination compounds as light-stable, nano-structured and anti-bacterial coatings for dental implant and restorative materials

Slenters, Tünde Vig ; Hauser-Gerspach, Irmgard ; Daniels, Alma U. ; Fromm, Katharina M.

In: Journal of Materials Chemistry, 2008, vol. 18, p. 5359-5362

Silver coordination polymer chains were deposited on Au(111) as a model surface, as well as on gold alloy and titanium as dental implant and restorative materials. The topography of the surface was analysed on the model substrate and it was found to be a nano-structured crystalline material. In vitro investigations in a flow chamber imitating the oral environment prove the anti-bacterial...
