Nanosensors in hydrogel enable tracking of transplanted cells

By Maja Bosanac
5 February 2013

nanosensorsResearches at the Johns Hopkins University School of Medicine have developed a method for in vivo monitoring of transplanted-cell viability. The researchers used nanoscale pH sensors and magnetic resonance imaging (MRI) to track liver cells previously transplanted into mice. This new method is likely to be an important tool for improving cell replacement therapies for conditions such as liver… »

tiras-butterflyAlthough micro aerial vehicles (MAVs) could be very useful in search and rescue, exploration and environmental monitoring missions, due to their small size they still lack maneuverability. Johns Hopkins University (JHU) engineers are using high-speed video cameras to figure out how butterflies manage to fly with amazing grace and agility in order to improve maneuvering… »


Hydrogel shows potential for scar-free skin burn recovery

One Comment29 December 2011

burn-hydrogel-1Johns Hopkins researchers have developed a simple wound dressing that included a specially designed hydrogel – a water-based, three-dimensional framework of polymers – that promotes the formation of new blood vessels and skin, including hair follicles. It could lead to greatly improved healing for injured soldiers, home fire victims and other people with third-degree burns…. »
