Excerpt:
A group of researchers at Montana Technological University has developed a portable electrospinning device with a confined electric field that can safely deposit bandages and drugs directly onto biological surfaces. The group describes the instrument — which they call the electrostatic and air driven device — in the Journal of Vacuum Science & Technology B, from AIP Publishing.
Instead of using the voltage difference between the tool and a surface to deposit the fibers, the new device uses air to spray the fibers out onto the surface, like a can of spray paint.
“In spray painting, pressurized gas forces direct particles toward a surface, creating a sort of deposited material,” said author Lane Huston, a mechanical engineering graduate student at Montana Tech. “Like spray painting, the EStAD device is used by directing its nozzle at the desired surface during operation, causing a fiber mat to be deposited onto that surface.”
By applying this spray paint-like mechanism, this device can be used to cover wounds and provide controlled drug release over time. The deposited fibers adhere to materials containing internal moisture, such as human skin.
