Summary:The synthesis of Au nanoparticles (NPs) in ionic liquid (IL) supported on biopolymers films applied in the investigation of antimicrobial activity was introduced as a new experimental practice for undergraduates in the nanotechnology discipline at the Department of chemistry, at University Federal of Rio Grande- FURG. The Au NPs were synthesized by reduction of tetrachloroauric acid complex trihydrate (HAuCl4.3H2O) in IL 1-n-butyl-3-methyl-imidazolium hexafluorophosphate (BMI.PF6) using sodium borohydride at room temperature. Subsequently, the Au NPs were supported in the biopolymers films using a solution of cellulose acetate dissolved in acetone. The biopolymers films containing supported Au NPs were applied in the investigation of antimicrobial activity against bacteria Escherichia coli e Staphylococcus aureus.
