| Summary: | Since the emergence of the SARS CoV2 virus, viral and antibacterial disinfection systems have become a global necessity, as well as their effective control and removal. In this context, the improvement of photocatalytic systems for the elimination of microorganisms may play a fundamental role. In this work, a photocatalytic disinfection system was developed and evaluated, based on additively manufactured Ti6Al4V parts using near-visible UV light. Several electrochemical and/or thermal treatments were optimized to obtain different nanostructured morphologies. The results show the effectiveness of the photocatalytic effect (∆R) on <i>E. coli</i> bacteria on different Ti6Al4V modified surfaces, reaching ∆R values between 0.4 and 2.4. |
