The Participants

Outline Objectives Background Research Conclusion Acknowledgments

Objectives Analyze the importance of size Synthesis of nanoparticles Identify and characterize nanoparticles in health and beauty

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

Size 1 nm = 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

Synthesis

Microscopy and Spectroscopy Instruments Dynamic Light Scattering (DLS) Ultraviolet-visible spectroscopy (UV/Vis) Scanning Electron Microscope (SEM) Transmission Electron Microscope (TEM)

Scanning Electron Microscope Electron Beam Magnification capabilities EDAX software Uses

Characterization-Scanning Electron Microscope 500 nm

Elemental analysis confirms the nanoparticles are gold EDAX Software 200 nm

Health and Beauty Synthetic vs. ‘natural’ make up Synthetic Natural

Conclusion Appreciation of nanotechnology and nanoparticles Successful synthesis of gold Application, Careers, Society

Future Work Continue to explore green synthesis of metallic nanoparticles Composition of make up Negative factors of nanoparticles to the environment
