Magnetoelektrische Kopplung - Duett auf Nano-Art

Ferroelektrische und -magnetische Eigenschaften voneinander abh�ngig in einem System zu nutzen, daran arbeiten Wissenschaftler schon seit langem. Einem Team vom Center for Nanointegration (CENIDE) der Universit�t Duisburg-Essen ist dies j�ngst in einem Komposit-System gelungen.

Ingested nanoparticle toxicity

Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.

Nanotechnology gold probes may offer valuable insight into cancer

Gold nanoprobes could allow scientists to study cancer cells in minute detail - using a highly-sensitive imaging technique known as FRET microscopy - with the aim of identifying tumour-causing properties. The nanoprobes could also be used to measure how effective medicines are, at a sub-cellular level of detail, while another application could be the identification of contaminants in food and water supplies.

Spinat und Nanodiamant?

Forscher der Universit�t Ulm haben mit Hilfe von Nanodiamanten Biosensoren entwickelt, die in der Lage sind, den Bluteisenwert zuverl�ssiger zu messen als herk�mmliche Verfahren. Ihnen ist es gelungen, die Magnetfelder der am Ferritin gebundenen Eisenionen durch ein diamantbasiertes hochsensibles Messverfahren zu erfassen.
