Researchers inject nanofiber spheres carrying cells into wounds to grow tissue
For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, ...
Nanoparticles disguised as red blood cells deliver cancer-fighting drugs
Researchers at the University of California, San Diego have developed a novel method of disguising nanoparticles as red blood cells, which will enable them to evade the body's immune system and deliver cancer-fighting drugs ...
Study shows deepwater oil plume in Gulf degraded by microbes
In the aftermath of the explosion of BP's Deepwater Horizon drilling rig in the Gulf of Mexico, a dispersed oil plume was formed at a depth between 3,600 and 4,000 feet and extending some 10 miles out from ...
Israeli team eyes jellyfish for super-absorbent material
Nanoparticles added to platelets double internal injury survival rate
(Phys.org)—Nanoparticles tailored to interact with platelets rapidly create healthy clots and nearly double the survival rate in the vital first hour after injury, new research shows.
Waste cooking oil makes bioplastics cheaper
"Bioplastics" that are naturally synthesized by microbes could be made commercially viable by using waste cooking oil as a starting material. This would reduce environmental contamination and also give high-quality plastics ...
BioSolar announces first sale of BioBacksheet—solar panel part made from cotton and beans
New process targets valuable green chemicals
(Phys.org) —Milk cartons, plastic bags, car seats... the list of items made from petroleum extends far beyond fuel, increasing our reliance on limited fossil resources. That's why researchers in the Great ...
Enzymes dig channels: Enzymatic etching used to build nano- and microscale surface topologies
(Phys.org)—In living systems, complex nano- and microscale structures perform a host of physical and biological functions. While two-dimensional patterns can be recreated fairly well with techniques like ...
Microencapsulation produces uniform drug release vehicle
Consistently uniform, easily manufactured microcapsules containing a brain cancer drug may simplify treatment and provide more tightly controlled therapy, according to Penn State researchers.
New technique can help nanoparticles deliver drug treatments
A Wayne State University researcher has successfully tested a technique that can lead to more effective use of nanoparticles as a drug delivery system.
Battery dissolves in water, holds promise for biomedical implants
Surfaces inspired by geckos can be switched between adhesive and non-adhesive states, study finds
Adhesives inspired by the gecko can be made to switch on and off reversibly and repeatedly. The key design parameters for these materials are identified in a study published in Journal of the Royal Society In ...
Small is good in quest to resolve water crisis
Can Peepoo stop the flying toilet? A small Swedish company believes so. At the World Water Forum in Marseille, it is promoting a cheap, smart fix for the world's billion slumdwellers.
