Nowadays, nanoparticles are effectively used in different areas. In the early days, physical and chemical methods were used in the synthesis of nanoparticles. Biosynthesis (green synthesis) appeared as an alternative to overcoming the toxic effects of chemically synthesized nanoparticles. In this study, it was characterized by the green synthesis of African grapefruit (Saintpaulia) and silver nanoparticles (AgNPs) by the leaf extract. The characterization resulted in the fact that nanoparticles of a wavelength of ~432 nm show spectrum and a global size of 40.4 nm. Antibacterial and biophilic inhibition activities against four Gram-positive and four Gram-negative bacterial substances of AgNP have been determined. In a concentration of 10 mM, silver nanoparticles have a bacteriosidal effect against all bacterial sugars. In the study of antibiotic activity, the highest inhibition percentage was achieved against Salmonella infantis in a concentration of 10 mM at 80.3%.

Today, nanoparticles are effectively used in different areas. Initially, physical and  chemical methods were used in the synthesis of nanoparticles. Biosynthesis (green synthesis) has  emerged as an alternative to overcome the toxic effect of chemically synthesized nanoparticles. In this  study, green synthesis of silver nanoparticles (AgNPs) with the leaf extract of African violet plant  (Saintpaulia) was carried out. As a result of the characterization, it was determined that nanoparticles  were formed at a spherical size of 40.4 nm with a spectrum showing a spectrum at a wavelength of 432  nm. Antibacterial and biofilm inhibition activities of AgNPs against four Gram-positive and four Gramnegative  were determined with bacterial strains. Silver nanoparticles at 10 mM concentration showed  bacteriocidal activity against all bacterial strains. In the antibiotic activity study, the highest inhibition  percentage was obtained against the Salmonella infantis strain at 80.3% at a concentration of 10 mM.
