Plaster me in!

That moment, when you slice your finger with the knife you were using to cut the carrots, or the day when you fell over in primary school and badly grazed your knee. Either way the First Aid kit is the first thing to reach for, and a plaster would be the first thing to hand.

Plasters not only protect the cut from any invading pathogens in the air, but it also helps to keep the wound moist for better healing. However, the DREADED moment always  occurs when washing your hands or going in the shower....The plaster always tumbles off and falls into a heap leaving a very fragile piece of skin exposed. Which, frankly hurts so much, when water splashes onto the wound.

Well, if this has happened to you, fear no more!

American scientists have designed a new form of plaster based upon the action of the parasitic worm Pomphorhynus laevis. The plaster is expected to be used (at the moment) specifically for burns patients. The 4 x 4 cm patch has essentially a bed of fine needles, which when applied to the body can attach to the skin, up to 3 times stronger than the regular plaster, which uses a sticky adhesive. Not only is this beneficial  but the scientists also think they could use the spikes for therapeutic purposes to administer medication subcutaneously.

Additionally, once the new spiked plaster is removed it inflicts less trauma on the tissues than the regular adhesive counterparts. Making it a very practical advance in pharmacological treatments.
