Second call for schools to participate in NANOYOU nanotechnology for the classroom

NANOYOU offers schools the opportunity to address European citizen's poor understanding of nanotechnologies as shown in recent surveys. It is a great chance for schools and teachers to receive first hand information on nanotechnologies and to discover the opportunities and risks of this discipline for present and future scientific development.

How bacteria make nano-syringes

For a successful infection, bacteria must outwit the immune system of the host. To this aim, they deliver so-called virulence factors through a transport channel located in the bacterial membrane. In some bacteria this transport channel is formed like a syringe, enabling them to inject virulence factors directly into the host cell. Scientists have now succeeded for the first time in elucidating basic principles of the assembly of this transport channel.

Engineers turn the stickiness of gold nanoparticles into an advantage

One property of gold nanoparticles stands in the way of many nanotechnological developments: They're sticky. Gold nanoparticles can be engineered to attract specific biomolecules, but they also stick to many other unintended particles - often making them inefficient at their designated task. MIT researchers have found a way to turn this drawback into an advantage.

Programmierbares DNA Nanopartikel-Ventil setzt gezielt Wirkstoffe frei

Damit die Dosis eines Medikaments kuenftig so niedrig wie therapeutisch moeglich gehalten werden kann, sollen die Wirkstoffe in Zukunft direkt zum Zielort im Organismus transportiert und dort erst freigesetzt werden. Dafuer sollen sie in Nanopartikel eingeschlossen werden, die ihre Fracht nur bei einem bestimmten pH-Wert, einer definierten Temperatur oder unter anderen spezifischen Bedingungen freigeben.
