Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming and error-prone step of DNA amplification. In a study published in the Dec. 20 online edition of Nature Nanotechnology, a team led by Boston University Biomedical Engineering Associate Professor Amit Meller details pioneering work in detecting DNA molecules as they pass through...

Shell of single-protein capsule degrades or remains intact based on environment Protein therapy "” the delivery of healthy proteins directly into human cells to replace malfunctioning proteins "” is considered one of the most direct and safe approaches for treating diseases. But its effectiveness has been limited by low delivery efficiency and the poor stability of proteins, which are frequently broken down and digested by cells' protease enzymes before they reach their intended...

TAU's new nano-material may revolutionize solar panels and batteries too A coating on windows or solar panels that repels grime and dirt? Expanded battery storage capacities for the next electric car? New Tel Aviv University research, just published in Nature Nanotechnology, details a breakthrough in assembling peptides at the nano-scale level that could make these futuristic visions come true in just a few years. Operating in the range of 100 nanometers (roughly one-billionth of a meter) and...

Platinum-catalyzed photosynthetic process creates high-yield sustainable source of hydrogen In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-energy process that outweighs the benefits of not using petroleum to power vehicles. New findings from a team of researchers from the University of Tennessee, Knoxville, and Oak Ridge National Laboratory,...

Rice University scientists yesterday unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online in the journal Nature Nanotechnology. "Plastics is a $300 billion U.S. industry because of...

A multidisciplinary team of UC researchers is the first to find an innovative and novel way to control an electron's spin orientation using purely electrical means. Their findings were recently published in the prestigious, high-profile journal "Nature Nanotechnology," in an article titled "All-Electric Quantum Point Contact Spin-Polarizer." For decades, the transistors inside radios, televisions and other everyday electronic items have transmitted data by controlling the movement of the...

New 'stereocenters' introduce triangular joints into otherwise linear nanomaterials Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. The work is described this week in the journal Nature Nanotechnology by Harvard University researchers led by Bozhi Tian and Charles M. Lieber. Among other...

University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications. Quantum dots"”often called artificial atoms or nanoparticles"”are tiny semiconductor crystals with wide-ranging potential applications in computing, photovoltaic cells, light-emitting devices and other technologies. Each dot is a well-ordered cluster of atoms, 10 to 50 atoms in...
