Affordable, Dissolving Microneedles Offer Needle Alternative

Mar-21-18 A new 3D-printed dissolving microneedle array offers an affordable and pain-free alternative to syringes.

While microneedle arrays offer a pain-free method of drug delivery, they typically require a specialized cleanroom for production, which can be too expensive for small companies. As a more affordable option, researchers from the University of Texas developed a method of printing microneedles, and then doing “post-print processing” to make the needles extremely sharp. In tests on pig skin, applying a bit of force caused the needles to break off in the skin, where they delivered their sample of dye molecules before dissolving over time.
