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.
If pathogens enter into our water supply network many people may fall ill quickly. To protect us against this biological threat, researchers have developed a detection system partly based on nanotechnology that can warn authorities in time.
Wissenschaftler der Uni Hamburg konnten erstmals ein funktionierendes Spintronik-Logik-Bauteil verwirklichen, das aus wenigen magnetischen Atomen aufgebaut ist. Beim Schalten des realisierten logischen Oder-Gatters ist im Gegensatz zu herkoemmlichen elektronischen Bauteilen kein Stromfluss noetig, da nur die magnetische Ausrichtung der Atome umgeschaltet wird.
Flash forward 20 years... What if our best efforts to lower carbon emissions, wean off fossil fuels, and plan for a soaring population weren't enough? Would we ask ourselves why we didn't take action sooner, transforming the ideas from our greatest innovators into the technologies needed to prepare for a more secure and sustainable future?
Adding a few graphene layers onto the conventional gold-film surface plasmon resonance (SPR) biosensor will boost up its sensitivity dramatically. The improved sensitivity comes from the graphene layer's increased adsorption of biomolecules and the graphene layer's optical modification to the SPR.
Researchers from the Vienna Center for Quantum Science and Technology at the University of Vienna and the Institute of Quantum Optics and Quantum Information at the Austrian Academy of Sciences used a quantum mechanical system in the laboratory to simulate complex many-body systems.
Researchers in the Materials Science and Technology division of the Naval Research Laboratory have recently demonstrated electrical injection, detection and precession of spin accumulation in silicon, the cornerstone material of modern device technology, at temperatures up to 225 degrees Celsius.
A world-first cattle vaccine based on nanotechnology could provide protection from the Bovine Viral Diarrhoea Virus (BVDV), which costs the Australian cattle industry tens of millions of dollars in lost revenue each year.
Intel Corporation today announced a significant breakthrough in the evolution of the transistor, the microscopic building block of modern electronics. For the first time since the invention of silicon transistors over 50 years ago, transistors using a three-dimensional structure will be put into high-volume manufacturing.
