Zusammenfassung: | The present study focused on Rosmarinus officinalis Linn. leaves extract (ROE) mediated synthesis of silver nanoparticles (AgNPs), selenium nanoparticles (SeNPs), reduced graphene oxide (rGO) and silver and selenium nanoparticles decorated on rGO nanomaterials (Ag&SeNPs@rGONM's) for its antibacterial and antifungal in silico mechanistic insight applications. In addition, the toxicity of the synthesized nanomaterials was evaluated using Artemia salina. The formation of AgNPs, SeNPs, rGO and Ag&SeNPs@rGONM's was completed within 1.0, 140, 120 and 144 h, respectively. Various optical and microscopic examinations were evident in the nanomaterial's synthesis. Further, the average size and stability of the synthesized nanomaterials were conformed through dynamic light scattering (DLS) and zeta potential analyzer, respectively. The synthesized Ag&SeNPs@rGONM's were pronounced promising results against Gram-negative bacteria of Escherichia coli and the results achieved from the route of entry and action, reactive oxygen species (ROS), and antioxidant nature of nanoparticles were evidence of its properties. Computational studies further supported these findings, indicating much of the phytochemicals present in ROE well interact with the bacterial surface proteins. Similarly, the synthesized Ag&SeNPs@rGONM's was effective against Fusarium graminearum and Alternaria alternata in a dose dependent manner than its original nanomaterials. In addition, the docking study also confirmed that rosmarinic acid and caffeic acid prominently interacted with the fungal proteins. Interestingly, Ag&SeNPs@rGONM's pronounced less toxic effect compared to AgNPs and SeNPs against Artemia salina, which shows its biocompatibility.
