Effect of AgNPs and AgNPs-go on the bioadhesion of <i>Pseudomonas aeruginosa</i> on stainless steel surfaces
With the aim of incorporating nanohybrid materials in antimicrobial coatings, the inhibition of the adhesion of Pseudomonas aeruginosa on 430 AISI stainless steel coupons exposed to AgNPs and AgNPs-GO solutions was studied. AgNPs were obtained by green synthesis, while AgNPs-GO by exsitu and in-situ...

| Sumario: | With the aim of incorporating nanohybrid materials in antimicrobial coatings, the inhibition of the adhesion of Pseudomonas aeruginosa on 430 AISI stainless steel coupons exposed to AgNPs and AgNPs-GO solutions was studied. AgNPs were obtained by green synthesis, while AgNPs-GO by exsitu and in-situ synthesis. Coupons were immersed in these solutions, to form a coating. Bacterial adherence values obtained were: 105-106 CFU.cm-2 for coupons without coating; 104-105 CFU.cm-2 for AgNPs-GO (in-situ) coupons and values lower than 102 CFU.cm-2 on AgNPs and AgNPs-GO (exsitu) coupons. These results were corroborated by scanning electron microscopy observations. |
