Zweite Fragebogenaktion zu Taetigkeiten mit Nanomaterialien in Deutschland

Die Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin (BAuA) unter Mitwirkung des Verbandes der chemischen Industrie (VCI), des Bundesverbandes der Deutschen Industrie e. V. (BDI) und des Bundesministeriums fuer Bildung und Forschung (BMBF) startet eine zweite Fragebogenaktion zu Taetigkeiten mit Nanomaterialien in Deutschland. Ein pragmatischer Ansatz fuer eine offene Risikokommunikation steht dabei im Mittelpunkt.

What’s the environmental footprint of your nanosilver T-shirt?

Several manufacturers are incorporating nano-sized particles of silver into, among other things, garments like socks and shirts to kill bacteria that cause odor. But does the silver stay in the socks or T-shirts? And what happens to it if it washes out? Also, what is the climate footprint of producing the required nanosilver? To answer these questions, a group of researchers have performed a cradle-to-grave life cycle assessment to compare nanosilver T-shirts with conventional T-shirts with and without biocidal treatment. For their assessment, the team used conventional T-shirts treated with triclosan, a commonly applied biocide to prevent textiles from emitting undesirable odors. The results show significant differences in environmental burdens between nanoparticle production technologies.

New patent: Template-synthesized DNA nanotubes

A method of forming DNA nanotubes composed entirely or predominantly from DNA that, The methods of the present invention form single layer or multilayer template-synthesized nanotubes where the bulk of the tube is composed of DNA, and the layers are held together by hybridization of complementary DNA strands. The DNA molecules making up these tubes may be varied as desired, and the DNA is capable of being released from the tube.

Cell signals via membrane nanotubes

Most of the body's cells communicate with each other by sending electrical signals through nano-thin membrane tubes. A sensational Norwegian research discovery may help to explain how cells cooperate to develop tissue in the embryo and how wounds heal.
