Researchers develop magnetically controlled dime-sized robot

Dynamic things come in small packages and that is true. The same has been evident in case of robotics which have taken huge leaps in terms of evolution. Recently we saw Harvard University’s RobotBee and bit before that tiny robots demonstrate real power by pulling a 3,900 pound car. Now it’s time for Ryan St. Pierre and Professor Sarah Bergbreiter from the University of Maryland to showcase their idea of nano robotics. Their original plan was to scale down an already miniscule robot like RHex, but it didn’t work that well due to locking of legs.

Spray-on bandage capable of protecting and healing serious wounds

Spray on bandage

Spray-on a surgical bandage and your wound would be dressed to perfection. Working on a new medical project, researchers from the University of Maryland have made a spray-on bandage that is made from biodegradable material which takes the shape of the wounded body part, protecting it from any kind of infections. First the researchers used commercial airbrush to spray-on the biodegradable bandage but then they decide to use a biodegradable polymer called poly (lactic-co-glycolic acid)-PLGA in a mixture of acetone to achieve the desired result. The spray-on bandage can lay fibers of diameter 370 nanometers and as soon as you spray the bandage onto the affected area, the acetone content in it evaporates.
