DNA is a useful building material for nanoscale structures. In a way similar to origami, a long single strand of DNA can be folded into nearly any three-dimensional shape desired with the use of short DNA fragments. The DNA nanostructure can also be equipped with specific docking sites for proteins. Researchers have now introduced a new method for attaching the proteins by means of special "adapters" known as zinc-finger proteins.
Today sees the announcement of full details of how an additional GBP50 million will be spent to keep the UK at the forefront of research into 'wonder material' graphene. Also below are details of further investment strands for graphene engineering and research technology.
Engineers have developed a prototype device that could power a pacemaker using a source that is surprisingly close to the heart of the matter: vibrations in the chest cavity that are due mainly to heartbeats.
Researchers from the NIST Center for Nanoscale Science and Technology have made a grating coupler that transmits over 45 % of the incident optical energy from a plane wave into a single surface plasmon polariton (SPP) mode propagating on a flat gold surface, an order-of-magnitude increase over any SPP grating coupler reported to date.
Students from Albany High School slipped on goggles and gloves to participate in hands-on classes today in the nanobioscience labs at the College of Nanoscale Science and Engineering (CNSE), part of the successful "NanoHigh" program developed by the City School District of Albany and CNSE.
A study that combines experimental observations of spider webs with complex computer simulations shows that web durability depends not only on silk strength, but on how the overall web design compensates for damage and the response of individual strands to continuously varying stresses.
A relatively fast, easy and inexpensive technique for inducing nanorods - rod-shaped semiconductor nanocrystals - to self-assemble into one-, two- and even three-dimensional macroscopic structures has been developed by a team of researchers with the Lawrence Berkeley National Laboratory.
A new form of proteins discovered by researchers at The University of Texas at Austin could drastically improve treatments for cancer and other diseases, as well as overcome some of the largest challenges in therapeutics: delivering drugs to patients safely, easily and more effectively.
Photodetectors made with graphene can process and conduct both light signals and electric signals extremely fast. Upon optical stimulation, graphene generates a photocurrent within picoseconds. Until now, none of the available methods were fast enough to measure these processes in graphene. Scientists have now developed a method to measure the temporal dynamics of this photo current.
