DNA Tunneling Detector Embedded in a Nanopore

Nanoletters- DNA Tunneling Detector Embedded in a Nanopore We report on the fabrication and characterization of a DNA nanopore detector with integrated tunneling electrodes. Functional tunneling devices were identified by tunneling spectroscopy in different solvents and then used in proof-of-principle experiments demonstrating, for the first time, concurrent tunneling detection and ionic current detection of DNA …

HULC Exoskeleton with Lift Assist Device

HULC is a lower-body, electro-hydraulically-powered exoskeleton designed to lift and carry heavy loads. It transfers weight through the machine’s frame to the ground, significantly reducing operator fatigue and exposure to injury. Additionally, HULC’s self-contained power supply eliminates external power cords or hydraulic lines that restrict deployment. The HULC Lift Assist Device allows single operators to …

Quasi-liquid memristors might make better brain implants

Researchers at North Carolina State University have demonstrated new “soft” electronic components, built from liquid metals and hydrogels. The scientists hope that such components—quasi-liquid diodes and memristors—will work better than traditional electronics to interface with wet squishy things, such as the human brain. Ju-Hee So, a graduate student in chemistry at NC State, described a …

Optical nanotube a step towards optical molecular electronics

Nature Nanotechnology – Electroluminescence from a single nanotube–molecule–nanotube junction The positioning of single molecules between nanoscale electrodes has allowed their use as functional units in electronic devices. Although the electrical transport in such devices has been widely explored, optical measurements have been restricted to the observation of electroluminescence from nanocrystals and nanoclusters and from molecules …
