New Technology Allows Microscopic Devices to Autonomously Find Their Way

Researchers from MIT have developed a new target-finding mechanism that allows microscopic devices to autonomously find their way to areas of a cell surface. Nature has developed a wide variety of methods for guiding particular cells, enzymes, and molecules to specific structures inside the body: White blood cells can find their way to the site […]

New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

Researchers Control Nanoparticles with Light and Magnets

A team of researchers has developed particles that can glow with color-coded light and be manipulated with magnets, improving the likelihood of tracking the position of the nanoparticles as they move within the body or inside a cell. A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, […]

New Mechanism of Photoconduction Could Lead to Next Generation Excitonic Devices

Physicists at MIT have discovered that shining light on a single layer of molybdenum disulfide (MoS2) can make the material less conductive. It’s a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered that […]

Nanoparticles Break the Symmetry of Light

Using an unusual kind of coupling between spin and the direction of propagation, physicists from the Vienna University of Technology are able to select the direction that nanoparticles can emit light into ultra-thin glass fibers. How can a beam of light tell the difference between left and right? At the Vienna University of Technology (TU […]

New Technology Enables Fast and Cheap Nanomanufacturing

A newly published study from MIT details how arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply. Luis Fernando Velásquez-García’s group at MIT’s Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: […]

Crumpled Graphene Forms Stretchable Supercapacitors

New research from engineers at MIT details how two-dimensional carbon “paper” can form stretchable supercapacitors to power flexible electronic devices. When someone crumples a sheet of paper, that usually means it’s about to be thrown away. But researchers have now found that crumpling a piece of graphene “paper” — a material formed by bonding together […]

New Sensor Tracks Down Cancer Biomarkers

Scientists from the University of Swansea have developed an ultrasensitive graphene biosensor that can detect molecules that indicate an increased risk of developing cancer. The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use, and was able to provide results in a matter of minutes, opening […]

Researchers Synthesize 2D Material Germanene

A newly published study details how a team of researchers successfully synthesized the 2D material germanene for the first time. Dubbed a “cousin of graphene”, the material, which is made up of just a single layer of germanium atoms, is expected to exhibit impressive electrical and optical properties and could be widely integrated across the […]
