Damage to cartilage may no longer have to be irreversible. A team of EPFL scientists has developed a smart hydrogel material that could promote cartilage regeneration. That would be great news for athletes, elderly, and people with conditions which lead to cartilage degeneration and arthritis. The advantage of this method is its ability to release… »
Collaboration between researchers at Emory University and Georgia Institute of Technology (Georgia Tech) resulted in the development of stem cells that can be directed by magnetic fields. Stem cells could soon be intravenous injected into the patient to treat heart diseases and vascular problems. By loading stem cells with superparamagnetic iron oxide nanoparticles (SPIOs), scientists… »
Inspired by the ability of pine cones to close their scales when wet and open them again once they have dried out, a group of researchers at ETH Zurich devised a new method to produce a variety of composite materials that are able to change their shape to a pre-programmed shape after being influence by… »
Aside their use in sci-fi, nanoparticles have emerged as a viable foundation for new ways to diagnose, monitor and treat disease. Current goal in development of nanoparticles used in medicine is to develop them in a way to selectively target only diseased cells, while leaving healthy cells unharmed. University of Florida (UF) researchers developed such… »
Nanoparticles could offer big hope in a small package to the many millions of people who are allergic to the nickel in everything from jewelry to coins and cell phones. The allergy causes a red, itchy rash when it comes into contact with their skin. Although some countries regulate the amount of the metal in… »
Some forms of plankton and bacteria have the ability to build an extra natural layer of nanoparticle-like armor. That ability has inspired chemists at the University of Warwick to create a remarkably simple way to give drug bearing polymer vesicles (microscopic polymer based sacs of liquid) their own armored protection. The technology could be used… »
We already wrote about several projects where pavement could be used to generate energy, and in this article we’re going to write about progress in technology used to clean the air with usage of a special pavement. Coated in titanium dioxide nanoparticles, pavement is able to reduce the amount of nitrogen oxide in the air…. »
Researchers at the University of Tennessee reported that English ivy nanoparticles may protect skin from UV radiation better than other metal-based nanoparticles such as titanium dioxide (TiO2). The team was led by Mingjun Zhang, an associate professor of biomedical engineering at the University of Tennessee, who previously discovered that English ivy owes its amazing clinging… »
