Metal Nanoparticle Synthesis Using Fruit Extracts as Reducing Agents and Comparative Studies with a Chemical Reducing Agent

Nanoparticle synthesis using plant extracts is biologically safe, cost-effective, and environment-friendly, hence attracting many researchers owing to its advantages over chemical or physical methods. In the current study copper silver nanoparticles have been synthesized by biological methods (using fruit extract). The leftover fruits collected from vendors were used for study, such as guava (Psidium guajava L), tomato (Solanum lycopersicum) a source of ascorbic acid, while lemon (Citrus limon (L.) Osbeck) orange X sinensis) citric acid. Quantification acid present in extract was performed Iodometric acid-base titrations, respectively, followed Thin Layer Chromatography (TLC) confirm their role nanoparticle production. characterized UV–visible (UV–VIS) spectroscopy Fourier transform infrared (FT-IR) spectroscopy. number particles produced with reducing agent more compared size structure similar those chemically.
