Public Release: 14-Apr-2016
Nanoscrolls created from graphene's imperfect cousin
Seeking an alternative, a team from MIT and Harvard University is looking to graphene oxide -- graphene's much cheaper, imperfect form. Graphene oxide is graphene that is also covered with oxygen and hydrogen groups. The material is essentially what graphene becomes if it's left to sit out in open air. The team fabricated nanoscrolls made from graphene oxide flakes and was able to control the dimensions of each nanoscroll, using both low- and high-frequency ultrasonic techniques.

Tumble-proof cargo transporter in biological cells
Ever wondered how molecular nanomotors work when transporting material such as organelles in the cell? Typically, nanomotors move along biopolymer filaments to go about their duties in the cell. In a new study published in EPJ E, Mu-Jie Huang and Raymond Kapral from the University of Toronto, Canada show that synthetic motors can attach to polymeric filaments and move along without changing either their shape or the direction in which they set out to move.

Researchers generate clean energy using bacteria-powered solar panel
For the first time ever, researchers at Binghamton University connected nine biological-solar (bio-solar) cells into a bio-solar panel. Then they continuously produced electricity from the panel and generated the most wattage of any existing small-scale bio-solar cells - 5.59 microwatts.

Dressed to kill: Tailoring a suit for tumor-penetrating cancer meds
Tiny capsules, called nanoparticles, are now being used to transport chemotherapy medicine to cancerous tumors. Drexel University researchers believe that the trick to gaining access to the pernicious cellular masses is to give these nanoparticles a new look.

Quantum dots enhance light-to-current conversion in layered semiconductors
Scientists combined the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor to produce a hybrid material that exhibited enhanced light-harvesting and energy transfer properties. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).

Wearable sweat sensor thanks to battery-free 'water pump' inspired by plants
Plants and trees soak up water in the soil by letting it vaporize through pores in the leaves. Scientists at Eindhoven University of Technology have now taken this principle to develop a sweat sensor through which the sweat itself flows at a steady rate, without external power, and is analyzed.

Intracellular recordings using nanotower electrodes
Toyohashi Tech researchers have developed an intracellular recording device, which has > 100-μm-long three-dimensional nanoscale-tipped microneedle-electrodes. Moreover, they demonstrated the needle penetrations into muscle cells and measured the signals. The nanoelectrode, whose size is longer than the conventional intracellular nanoelectrode (< 10-μm long), has the potential to be used in cells that are deep within a tissue, such as cells in brain slices or brain in vivo, thus accelerating the understanding of the brain.

Magnetic delivery of therapeutic enzymes paves the way for targeted thrombosis treatment
Researchers have fabricated a new magnetically controlled material composed of enzymes entrapped directly within magnetite particles. Combined with water, it forms a stable solution that can be used for safe intravenous injection for medical purposes, in particular, for targeted treatment of cancer and thrombosis. Previously, the synthesis of similar materials involved using additional components that impaired the magnetic response and enzymatic activity as well as created obstacles for intravenous injection into the human body.
