Hot Article: Electrochemistry-controlled metal ion release from silicone elastomer nanocomposites through combination of different metal nanoparticles

Researchers in Germany have achieved metal ion release from a silicone matrix by an electrochemistry-controlled method.

Synergistic metal ion release from a silicone matrix filled with silver and copper as well as silver and gold nanoparticles (NPs) was investigated. It was found that silver NPs enhanced the release of copper ions, whereas gold NPs did not enhance the release of silver ions. The mechanism of the release of the less noble metal nanoparticles is based on ion-mediated electrochemistry and not contact corrosion of both elements. This work shows potential in the design of time- and rate-controlled bioactive nanocomposites.
