Fabrication of antibacterial TiO[sub]2 nanostructured surfaces using the hydrothermal method
Niharika Rawat, Metka Benčina, Ekaterina Gongadze, Ita Junkar, Aleš Iglič
Izvirni znanstveni članek
Oznake: titanium;surface modification;microstructure;nanostructure;cell response;biocompatibility;
Implant-associated infections (IAI) are a common cause for implant failure, increased medical costs, and critical for patient healthcare. Infections are a result of bacterial colonization, which leads to biofilm formation on the implant surface. Nanostructured surfaces have been shown to have the po ...

Bio-performance of hydrothermally and plasma-treated titanium
Metka Benčina, Niharika Rawat, Katja Lakota, Snežna Sodin-Šemrl, Aleš Iglič, Ita Junkar
Izvirni znanstveni članek
Oznake: cardiovascular disease;metallic stents;hydrothermal treatment;non-thermal plasma treatment;TiO$_2$;
The research presented herein follows an urgent global need for the development of novel surface engineering techniques that would allow the fabrication of next-generation cardiovascular stents, which would drastically reduce cardiovascular diseases (CVD). The combination of hydrothermal treatment ( ...
