Universal DNA Reader May Advance Faster, Cheaper Sequencing (redOrbit)
Image Caption: As a single chemical base of DNA (blue atoms) passes through a tiny, 2.5nm gap between two gold electrodes (top and bottom), it momentarily sticks to the electrodes (purple bonds) and a small increase in the current is detected. Each of the chemical bases of the DNA genetic code, abbreviated A, C,... »
Carbon Nanotubes For Genetic Sequencing (redOrbit)
Image Caption: In the current issue of Science, Stuart Lindsay, director of Arizona State University’s Center for Single Molecule Biophysics at the Biodesign Institute, along with his colleagues, demonstrates the potential of a new DNA sequencing method in which a single-stranded ribbon of DNA is threaded through a carbon nanotube.

Small Optical Force Can Budge Nanoscale Objects (redOrbit)
Image Caption: Scanning electron micrograph of two thin, flat rings of silicon nitride, each 190 nanometers thick and mounted a millionth of a meter apart. Light is fed into the ring resonators from the straight waveguide at the right. Under the right conditions optical forces between the two rings are enough to bend the... »
Scientists Develop DNA Origami Nanoscale Breadboards For Carbon Nanotube Circuits (redOrbit)
Image Caption: In (a), single-wall carbon nanotubes labeled with “red” and “blue” DNA sequences attach to anti-red and anti-blue strands on a DNA origami, resulting in a self assembled electronic switch. In (b), an atomic force microscopey image of one such structure. The blue nanotube appear brighter because it is on top of the... »
