Antimicrobial Activity of MgB<sub>2</sub> Powders Produced via Reactive Liquid Infiltration Method
We report for the first time on the antimicrobial activity of MgB<sub>2</sub> powders produced via the Reactive Liquid Infiltration (RLI) process. Samples with MgB<sub>2</sub> wt.% ranging from 2% to 99% were obtained and characterized, observing different levels of grain agg...

| description | We report for the first time on the antimicrobial activity of MgB<sub>2</sub> powders produced via the Reactive Liquid Infiltration (RLI) process. Samples with MgB<sub>2</sub> wt.% ranging from 2% to 99% were obtained and characterized, observing different levels of grain aggregation and of impurity phases. Their antimicrobial activity was tested against <i>Staphylococcus aureus</i> ATCC BAA 1026, <i>Enterococcus faecalis</i> ATCC 29212, <i>Escherichia coli</i> ATCC 25922, <i>Pseudomonas aeruginosa</i> ATCC 27853, and <i>Candida albicans</i> ATCC 10231. A general correlation is observed between the antibacterial activity and the MgB<sub>2</sub> wt.%, but the sample microstructure also appears to be very important. RLI-MgB<sub>2</sub> powders show better performances compared to commercial powders against microbial strains in the planktonic form, and their activity against biofilms is also very similar. |
