Biological Decontamination of Radionuclides in Industrial and Environmental Water Using a New Highly Radioresistant Microalga

Rivasseau C., de Gouvion Saint Cyr D., Atteia A., Gromova M., Farhi E., Commissariat à l’Energie Atomique, FR

Nuclear energy technologies generate radioactive and chemically toxic compounds including mainly carbon-14 and radioactive metals. Treatment processes rely on physico-chemical methods, which, though efficient and robust, do not completely remove carbon-14 and are not adapted [...]

Luminescent Terbium/Europium chelates-based Silica Nanoparticles : Stability and Incorporation Efficiency measured by Radioactive Probe

Wartenberg N., Raccurt O., Mazzanti M., Imbert D., Bourgeat-Lami E., Commissariat à l’Energie Atomique, FR

We describe an original method based on europium-chelated radioactive measurements to investigate and compare the incorporation (by a reverse microemulsion-mediated sol-gel process without covalent bond) and the stability of two different organolanthanides into silica nanoparticles. [...]

Specific device for cells sampling

Cosnier M.L., Martin F., Ratel D., Berger F., Caillat P., Commissariat à l’Energie Atomique, FR

We developed a miniaturized biopsy tool for harvesting molecules of interest in delicate areas such as brain. This tool permits harvesting of intact cells permitting genomic analysis on these cells. The sampling tool is manufactured [...]

Dispersion and incorporation of optical nanotracers

Samuel J., Raccurt O., Poncelet O., Tillement O., Tardif F., Commissariat à l’Energie Atomique, FR

Silica fluorescent nanoparticles of 40nm diameter are synthesized by a reverse microemulsion process. Numerous industrial applications involve the homogeneous incorporation of nanoparticles into a polymer matrix. Nevertheless, because of their low size, nanoparticles tend to [...]
