Ag-surfaces sputtered by DC and pulsed DC-magnetron sputtering effective in bacterial inactivation: Testing and characterization

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Cristina del Socorro Lonfat, Oualid Baghriche

This study addresses the deposition of active, uniform nanoparticulate Ag-thin films on polyester textiles by DC-magnetron sputtering (DC) and pulsed DC-magnetron sputtering (DCP). The deposition of Ag on the polyester fiber was observed to be the function ...

Innovative TiO2/Cu Nanosurfaces Inactivating Bacteria in the Minute Range under Low-Intensity Actinic Light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche

The bacterial inactivation of E. coli by cotton TiO2/Cu DC-magnetron sputtered thin films was investigated in the dark and under low-intensity actinic light. The TiO2/Cu sputtered layers revealed to be sensitive to actinic light showing the spectral charac ...

Photocatalysis/catalysis by innovative TiN and TiN-Ag surfaces inactivate bacteria under visible light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche

This study presents the design, preparation, testing and characterization of TiN and TiN-Ag nanoparticulate films leading to photocatalytic and catalytic inactivation of Escherichia coli. When Ti was sputtered in N2 atmosphere, the TiN films unexpectedly r ...

High power impulse magnetron sputtering (HIPIMS) and traditional pulsed sputtering (DCMSP) Ag-surfaces leading to E. coli inactivation

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Oualid Baghriche

This study addresses the high power impulse magnetron sputtering (HIPIMS) deposition of Ag-nanoparticle films on polyester and the comparison with films deposited by direct current pulsed magnetron sputtering (DCMSP). The first evidence is presented for th ...

Effect of the spectral properties of TiO2, Cu, TiO2/Cu sputtered films on the bacterial inactivation under low intensity actinic light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche

Bacterial inactivation by TiO2, Cu and TiO2/Cu DC-magnetron sputtered thin films was systematically investigated in the dark and under low intensity visible/actinic light. Low intensity actinic light led to a fast 6log10 (complete) bacterial inactivation w ...

Design, testing and characterization of innovative TiN–TiO2 surfaces inactivating bacteria under low intensity visible light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche

Ti was sputtered in a plasma chamber under a N2 atmosphere, depositing TiN films on polyester fibers. These films show a significant adsorption in the visible spectral region. A TiN layer 50 nm thick sputtered for 3 min under low intensity/actinic visible ...

E. coli Inactivation by High-Power Impulse Magnetron Sputtered (HIPIMS) Cu Surfaces

César Pulgarin, Juan Kiwi, Andrzej Kulik, Oualid Baghriche

This study reports HIPIMS-sputtered samples of Cu-particulate films with currents at 6 and 60 amps leading to E. coil inactivation. The Cu coverage and nanoparticle structure of the fibers is reported by TEM. Evidence is presented of redox processes in the ...
