Electrospinning device sprays bandages directly onto wounds

摘要

Researchers at Montana Technological University of Butte, Montana, USA, have developed a portable electrospinning device with a confined electric field that can safely deposit bandages and drugs directly onto biological surfaces, such as skin wounds. Most electrospinning methods require high voltages, which makes them unsuitable for use on biological materials. However, the US researchers have combined an electrospinning device having a smaller electric field with pressurized gas, which they call the electrostatic and air-driven device (EStAD). The group describes the instrument in Journal of Vacuum Science & Technology B~((1)). The device operates like a paint sprayer to deposit a fibre mat safely onto the surface of the skin. EStAD has so far been tested on a porcine skin incision and a gloved human hand.
