Scientists create spray-on bandages that could save lives in remote areas

According to a study published in the Journal of Vacuum Science & Technology, innovative spray-on bandages could help protect wounds and deliver life-saving drugs in far-flung places where immediate medical care is not available. Lane Huston, author of the study told the media that scientists have used a technique called electrospinning to create 'bottled bandages' that spray a thin layer of fibers on damaged skin like spraying paint on a wall. Huston claimed that it is the first demonstration of depositing the drug-delivering fibers directly on a wound safely. By applying this spray paint-like mechanism, this device can be used to cover wounds and provide controlled drug release over time, he added.

The technique might expose skin to electricity

The technique of electrospinning is used in industries to wrap, filter and insulate various commercial products. Yet the cons of the technique involve exposure to high voltage electricity that could be dangerous to human skin. The study states that the scientists have developed an electrospinning device with a smaller electric field that could safely deposit bandages onto the skin. The new device uses air to spray fibers onto the surface, instead of using the voltage difference between the tool and a surface to deposit the fibers.

Scientists aim to help doctors and patients in rural areas

In spray painting, pressurized gas forces direct particles towards a surface, creating deposited material. Like spray painting, the device is used by directing its nozzle at the desired surface during operation, causing a fiber mat to be deposited on that surface, said Huston. The scientists have successfully tested the spray-on pigs and a gloved human hand, as per the study. The global tapes and bandages market is worth around $5.5bn (£4.3bn). Researchers aim to help doctors and patients in rural areas with their discovery. Huston further said that the bandage material, as well as the drug used, can be chosen on-demand as the situation warrants, making modular and adaptable drug delivery accessible in remote locations.
