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.

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...

Antimicrobial coatings for implant surfaces

Brunetto, Priscilla S. ; Fromm, Katharina M.

In: Chimia, 2008, vol. 62, no. 4, p. 249-252

Body-foreign materials are used more and more frequently in our lives: joint implants (hips, knees, fingers, etc.), catheters, pacemakers, dental and aesthetic implants, etc. The increasing numbers of patients requiring such implants also raises the absolute numbers of implant-related infections. Thus, it is known that body-foreign materials are prone to bacterial adhesion and subsequent biofilm...
