Abstract
This study investigates the bactericidal properties of ternary Zr-Cu-Ag thin film metallic glasses (TFMGs) after femtosecond laser texturing. Laser-induced periodic surface structures (LIPSS) significantly enhance antibacterial activity, preventing bacterial proliferation. Microscopic chemical and crystallographic changes at the surface are analyzed using Scanning Transmission Electron Microscopy and high-resolution Energy Dispersive X-ray spectroscopy, correlating these with ion-release measurements to elucidate the underlying mechanisms. The influence of the atmosphere during laser irradiation is also examined. Our findings highlight the potential of laser-modified TFMGs for antibacterial applications.

H. Bruhier is associate professor at Université Jean Monnet (France) since September 2025, conducting research at Laboratoire Hubert Curien. He earned an engineering degree and M.S. in photonics and surface science (2019), followed by a PhD in plasmonics (2023), honored with a “Young PhD Excellence Award.” As a postdoc at MatéIS (INSA Lyon), he studied ultrafast laser irradiation of metals for biomedical uses. His current work explores how ultrashort laser pulses modify materials, analyzing surface changes for diverse applications.
