Body Heat-Powered Drug Delivering Bandages Means No More Needles

The only painful part of wearing an adhesive bandage is have to peel them off , so researchers at Purdue University’sBirck Nanotechnology Centerhave developed a way to turn Band - Aids into a nearly nuisance free option to needle . By integrating a midget heat - power ticker , adhesive patch could automatically pitch medication to a patient without the indigence for a painful scratch .

What ’s most interesting is that the tiny heart is n’t tamp down full of nano - scale sized bleeding - sharpness engineering . Instead , a small chamber sandwich between layers of flexible polymer is filled with nothing more than sugar and baker ’s yeast . When the patch is stick to the skin and moistened , the H2O and the patient ’s body heat causes the yeast and clams to fermentation which produce atomic number 6 dioxide . And as the CO2 gas make the chamber to expand , it pushes against the flexible polymer membrane which could one sidereal day be covered in microneedles that mechanically inject a given eccentric of medication through the skin without the patient ever feeling a affair .

ThePurdue researchersaren’t the first to search the possibilites of the microneedle glide path , but the developing of their fermentation pump means that medicinal patches could be implausibly trashy to create , and easy to use . And somehow slap a Phenaphen darn on your forehead just seems like it would be far more in force than taking a pill . [ Purdue UniversityviaGizmag ]
