1) Nanochemistry focuses on designing and producing innovative materials and technologies.However there are concerns regarding safety and eco-impact a) Identify 2 areas where nano materials could have a strong impact in the future and describe how nano materials can be used in 2 types of applications within each of these areas. b) Explain 1 possible chemical approach that could be useful for reducing the cytotoxicity effects of toxic nanoparticles (i.e. CdSe QDs)? c) What would you think is most important in what concerns safety of nano materiaks forbio-nano applications: size, shape or surface? Explain your reasoning for your choice.
