Abstract:The work presented will include the use of Daphnia magna to study the ecotoxicity of bare and functionalized gold-silica nanoshells and surface enhanced Raman scattering based imaging techniques (SERSI) to locate nanoshells within Daphnia magna. This species is still relatively novel for quantifying the potential ecotoxicity of nanoparticles, though a few studies have been conducted with commercially available particles. Our groupís ability to synthesize, functionalize and characterize the particles being tested significantly improve the ability to separate potential toxicity of the materials tested from any matrix effects coming from the use of commercially obtained nanoparticle systems.
