Title: Synthesis of silver nanoparticles (agnps) using (coriandrum sativum) cilantro extract as a reducing agent: exploring antimicrobial and catalytic activities
Biography: Alfredo Leal
The production of silver nanoparticles through the use of green synthesis (coriandrum sativum), is carried out due to its variety of applications such as bactericides, biomedical applications, water treatment, the medical-pharmaceutical and food industry. In this research work coriander extract (coriandrum sativum) is used, which contains alkaloids, flavonoids, saponins and steroid compounds that act as a reducing and stabilizing agent. The materials used in this work consisted of five different extracts of coriander (coriandrum sativum), in addition to two AgNO3 solutions of 10 and 100 mM, the presence of AgNPs in the solution was identified by UV-vis spectrophotometer (with wavelength between 250-290 nm The size of the nanoparticles AgNps was determined Via DSL (lasser) -ISO- (13310), it is between 20-40 nm.The optimization of the results was obtained by varying the volume of the extract, the pH, temperature, and reaction time were determined at intervals of 0-3, 3-7 days respectively Biosynthesized AgNPs exhibited antibacterial and catalytic activity against the strains E.Coli (Gram negative), Aureas Estrafilocos (Gram Positive) and Aspergillius niger (Fungus). It was discovered that biosynthesized AgNPs have a greater inhibitory action against E. coli & anti-inflammatory and healing properties.
