“…Citrus paradisi, a member of the Rutaceae family, is a perennial species. This plant contains narirutin and naringin, flavanones, ferulic and p-coumaric acids, vanillic, gallic acids phenolic acids, carotenoids, flavonoids, terpenoids, essential oils, and ascorbic acid, which have numerous health benefits due to their pharmacologically active properties (Gupta et al, 2010;Anupama Prasad et al, 2023;Kumar et al, 2020) The work aims to synthesize selenium nanoparticles using an extract from Citrus paradisi plant leaves in an environmentally friendly, cost-effective, and simple approach. The properties of the nanoparticles were characterised, and their antibacterial activities were investigated.…”
