Antimicrobial Activity of MgB(2) Powders Produced via Reactive Liquid Infiltration Method

We report for the first time on the antimicrobial activity of MgB(2) powders produced via the Reactive Liquid Infiltration (RLI) process. Samples with MgB(2) wt.% ranging from 2% to 99% were obtained and characterized, observing different levels of grain aggregation and of impurity phases. Their ant...

description We report for the first time on the antimicrobial activity of MgB(2) powders produced via the Reactive Liquid Infiltration (RLI) process. Samples with MgB(2) 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 Staphylococcus aureus ATCC BAA 1026, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, and Candida albicans ATCC 10231. A general correlation is observed between the antibacterial activity and the MgB(2) wt.%, but the sample microstructure also appears to be very important. RLI-MgB(2) powders show better performances compared to commercial powders against microbial strains in the planktonic form, and their activity against biofilms is also very similar.
