Description

With the rapid development of nanotechnology engineered nanoparticles will eventually enter the environment. The interactions between engineered nanoparticles with naturally organic molecules, aquatic organisms, and plant species determine the fate of these nanoparticles in ecological systems and the food chain, and present vast new opportunities for multidisciplinary research. In this presentation, the effects of adsorption of semiconducting quantum dots on the photoactivities of algae, one type of single-celled plants, will be discussed. The solubility of carbon-based nanoparticles, from fullerene C70 to multiwalled carbon nanotubes, will be compared in natural organic matter with respect to their morphology. Using rice and pepper plants as model systems, experimental results showing the uptake, translocation and generational transmission of fullerene C70 will be presented.
