Resumen:
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 ex-situ 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 (ex-situ) coupons. These results were corroborated by scanning electron microscopy observations
