In this animation, the cell membrane is encountered by a "Trojan horse" made of a cationic cell penetrating peptide and a gene which both are anchored to a gold nanoparticle carrier that brings the bioconjugate to the site inside the cell nucleus. Both molecules require different media and pH, so it would be difficult to simply mix everything. But subsequent addition of the biomolecules to a continuous gold nanoparticle source (with its origin from laser ablation of a wire) flow in water could provide the bivalent gold nanoparticle bioconjugates.<br /> -----: The projekt is supported by Deutsche Forschungsgemeinschaft (research see <a href="http://www.uni-due.de/barcikowski/forschen.htm">http://www.uni-due.de/barcikowski/forschen.htm</a>). clean nanoparticle colloids for medical and catalysis application tag:www.nanopaprika.eu,2012-02-06:1612324:Video:167555 2012-02-06T15:15:37.417Z Dr. Stephan Barcikowski http://www.nanopaprika.eu/profile/DrStephanBarcikowski <a href="http://www.nanopaprika.eu/video/clean-nanoparticle-colloids-for-medical-and-catalysis-application"><br /> <img alt="Thumbnail" height="180" src="http://api.ning.com:80/files/Zx2GNpAjY-DPdjfvBIHX8YSUrebIgdNOSe993hXFiFGj9i0NwnZkctTsmI8QQWSthx8S4lqBt9jLSmiEunf8ggYrdNkw0pm5/493145114.jpeg?width=240&amp;height=180" width="240"></img><br /> </a> <br></br>"Naked" nanoparticles for medical application and catalyst surfaces which require high purity: Luckily, the nanoparticles made physically by laser ablation are free of residual chemicals (free of ligands) that may cause unwanted cross-effects or blocking of the… <a href="http://www.nanopaprika.eu/video/clean-nanoparticle-colloids-for-medical-and-catalysis-application"><br /> <img src="http://api.ning.com:80/files/Zx2GNpAjY-DPdjfvBIHX8YSUrebIgdNOSe993hXFiFGj9i0NwnZkctTsmI8QQWSthx8S4lqBt9jLSmiEunf8ggYrdNkw0pm5/493145114.jpeg?width=240&amp;height=180" width="240" height="180" alt="Thumbnail" /><br /> </a><br />"Naked" nanoparticles for medical application and catalyst surfaces which require high purity: Luckily, the nanoparticles made physically by laser ablation are free of residual chemicals (free of ligands) that may cause unwanted cross-effects or blocking of the surface.
