Background and Motivation
• Daizy Philip-green synthesis of metallic
nanoparticles
• Can we actually make silver and gold?
• Nanotechnology and nanoparticles
awareness

Size
• 1 nm = 10-9 m
• Nanoparticle =?
• Why is size importance?
– Chemical features
– Reactivity
– Color

Synthesis of Metallic Nanoparticles
• Green synthesis
– Gold via Honey
– Gold via Hibiscus plant
– Silver via chemicals & Geranium plant
