Publication number: 20120122146Abstract: There is provided an insect model for determining the penetration of nanoparticles through the BBB. The model is also directed to the use of insects for studying the environmental safety of nanoparticles. The particles are administered into the hemolymf of an insect having a BBB, such as the locust, and the uptake into the brain is analysed. Thus, in this model it is possible to investigate the potential up-take into the brain of nanoparticles circulating in the blood.Type: ApplicationFiled: August 10, 2010Publication date: May 17, 2012Applicant: ENTOMOPHAM APSInventors: Peter Aadal, Gunnar Andersson, Olga Andersson

Patent number: 8088614Abstract: Methods and compositions are provided for producing purified oil from an organism, whether these organisms are wild type, selectively bred or genetically modified, and are suitable for the large scale production of an oil product. The organism may be an animal, a plant or a microorganism such as yeast, bacteria or algae. The organism is processed to create a biomass which can be extracted to remove the lipids contained within the biomass. The extraction produces a crude extract rich in lipids and containing residual contaminants. These contaminants are removed by contacting the crude extract with a composition that comprises a nanomaterial. Subsequently an oil product is recovered which is substantially free from residual contaminants, such as pigments.Type: GrantFiled: November 13, 2007Date of Patent: January 3, 2012Assignee: Aurora Algae, Inc.Inventors: Bertrand Vick, Matthew Caspari, Guido Radaelli

Publication number: 20110298149Abstract: An inorganic nanowire having an organic scaffold substantially removed from the inorganic nanowire, the inorganic nanowire consisting essentially of fused inorganic nanoparticles substantially free of the organic scaffold, and methods of making same. For example, a virus-based scaffold for the synthesis of single crystal ZnS, CdS and free-standing L10 CoPt and FePt nanowires can be used, with the means of modifying substrate specificity through standard biological methods. Peptides can be selected through an evolutionary screening process that exhibit control of composition, size, and phase during nanoparticle nucleation have been expressed on the highly ordered filamentous capsid of the M13 bacteriophage. The incorporation of specific, nucleating peptides into the generic scaffold of the M13 coat structure can provide a viable template for the directed synthesis of a variety of materials including semiconducting and magnetic materials.Type: ApplicationFiled: March 4, 2011Publication date: December 8, 2011Inventors: Angela M.
