Ausgerichtete DNA-Drähte für die Nanoelektronik

Da die anhaltende Miniaturisierung elektronischer Bauelemente bald an ihre physikalischen Grenzen stößt, suchen Forscher nach neuen Herstellungsmethoden. Einen aussichtsreichen Ansatz liefert DNA-Origami, bei dem sich Einzelstränge des Biomoleküls selbstständig zu beliebig geformten Nanostrukturen zusammenfinden.

Bacterial spores as building blocks for nanogenerators (w/video)

A new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water, according to research conducted at the Wyss Institute of Biologically Inspired Engineering at Harvard University. Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.

New quantum dots herald a new era of electronics operating on a single-atom level

New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of Warsaw. The materials and elements used to form these structures allow us forecast new trends in solotronics - a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.
