Swarms of tiny "microgrippers" used to perform biopsies

By - April 29, 2013 3 Pictures
When procuring tissue samples for medical diagnosis, doctors have been confined to bulky and invasive forceps. But with recent successful experiments in pigs, we may see doctors switching from the single forceps to hordes of a thousand "microgrippers." These metal discs, each only 300 micrometers in size, are designed to snip bits of tissue when introduced en masse into the body and then be easily retrieved by a doctor. Their small size, added to the fact that they need no batteries, tethers or wires, belies their complexity and autonomy in function, which could allow the microgrippers to provide diagnoses earlier, more easily, and with less trauma.

Sulfur-based polymers open door to a new class of battery

By - April 19, 2013 2 Pictures
Whether sulfur is a by-product or a waste product of oil refinement and coal combustion depends on how you slice it. Certainly, some of that sulfur can be put to use producing sulfuric acid, fertilizer and other chemicals, but much of it is accumulating into stockpiles that are expensive to maintain (due to the need to neutralize acidic run-off). Researchers at the University of Arizona think more of that sulfur could be put to use thanks to a new chemical process that uses sulfur to make plastics that may one day be used to make a new generation of lighter, more efficient lithium-sulfur batteries.

New transparent, flat, flexible image sensor has potential for gesture control displays

By - February 21, 2013 2 Pictures
A research team from the Johannes Kepler University Linz in Austria has developed an image capturing device using a single sheet of polymer that is flat, flexible and transparent. The researchers say the new image sensor could eventually find its way into devices like digital cameras and medical scanners, and that it may help to usher in a new generation of gesture-controlled smartphones, tablets and TVs.

Scientists develop "eco-friendly" antibacterial material

By - February 15, 2013 1 Picture
Because they’re known for being effective killers of bacteria, silver nanoparticles have been finding their way into a wide variety of antimicrobial materials. There are concerns, however, regarding the consequences of those nanoparticles being shed by the material and entering the environment. In particular, there are worries that through continuous low-level exposure to the nanoparticles, bacteria could develop a resistance to them. Now, researchers from Sweden’s KTH Royal Institute of Technology have announced the development of a new type of antibacterial material, that they claim won’t cause such problems. Read More

Polymer patches could replace needles and enable more effective DNA vaccines

By - January 29, 2013 1 Picture
Taking a two-month-old in for vaccination shots and watching them get stuck with six needles in rapid succession can be painful for child and parent alike. If the work of an MIT team of researchers pans out, those needles may be thing of the past thanks to a new dissolvable polymer film that allows the vaccination needle to be replaced with a patch. This development will not only make vaccinations less harrowing, but also allow for developing and delivering vaccines for diseases too dangerous for conventional techniques. Read More
