The World Health Organization (WHO) reports that the emergence of multidrug-resistant and slow advent novel more potent antitumor antimicrobial chemotherapeutics continue to be highest concern for human health. Additionally, stability, low solubility, negative effects existing drugs make them ineffective. Studies into alternative tactics tackle such tenacious diseases was sparked by anticancer antibacterial. Silver (Ag) gold (Au) nanoparticles (NPs) were created from Trichoderma saturnisporum, much productive fungal strain. Functional extracellular enzymes proteins carried out activities synthesis capping generated nano-metals. Characterization done on obtained Ag-NPs Au-NPs through UV-vis, FTIR, XRD, TEM, SEM. versus methicillin-sensitive Staphylococcus aureus (MSSA) methicillin-resistant (MRSA), Pseudomonas aeruginosa, Klebsiella pneumoniae, antibacterial assessed. In particular, effective against pathogenic bacteria than Au-NPs. Furthermore, antibiofilm study shown had activity Ag-NPs. Interestingly, applying DPPH procedure, these noble metallic NPs antioxidant activity, in which IC50 73.5 μg/mL 190.0 μg/mL, respectively. According cytotoxicity evaluation results, alteration cells as loss their typical shape, partial or complete monolayer, granulation, shrinking, cell rounding with normal Vero 693.68 661.24 Au-NPs, While cancer (Mcf7) 370.56 394.79 produced via green have potential employed medical industry beneficial nanocompounds.
