Micromotors have been used to treat a bacterial infection in the stomach for the first time, nanoengineers at the University of California San Diego report. The tiny vehicles, each about half the width of a human hair, swim rapidly throughout the stomach while neutralizing gastric acid and then release their cargo of antibiotics at the… Read more

Some biochemistry laboratories fashion proteins into complex shapes, constructing the DNA nanotechnological equivalent of Baroque or Rococo architecture. Yamuna Krishnan, however, prefers structurally minimalist devices. Said Krishnan, University of Chicago professor of chemistry: “Our lab’s philosophy is one of minimalist design. It borders on brutalist. Functional with zero bells and whistles. There are several labs… Read more

Researchers have developed a nanoscale machine made of DNA that can randomly move in any direction across bumpy surfaces. The “walker” could potentially roam the human body in search of cancerous cells and tag them for medical imaging or drug targeting. Previously, nanoparticle walkers were only able to walk on precise and programmed one- and… Read more

Scientists from Los Alamos National Laboratory, in collaboration with a group at the University of Illinois at Urbana-Champaign, the Lawrence Berkeley National Laboratory’s Advanced Light Source and other researchers nationwide, have realized a nanoscale, artificial magnet by arranging an array of magnetic nano-islands along a geometry that is not found in natural magnets. Los Alamos… Read more

New research could revolutionize the slow, cumbersome and expensive process of detecting the antibodies that can help with the diagnosis of infectious and auto-immune diseases such as rheumatoid arthritis and HIV. An international team of researchers have designed and synthetized a nanometer-scale DNA “machine” whose customized modifications enable it to recognize a specific target antibody… Read more
