A 3D printed vaccine patch offers vaccination without a shot

Scientists at Stanford University and the University of North Carolina at Chapel Hill have created a 3D-printed vaccine patch that provides greater protection than a typical vaccine shot. The trick is applying the vaccine patch directly to the skin, which is full of immune cells that vaccines target. The resulting immune response from the vaccine […]

A genetic patch to prevent hereditary deafness

They can hear well up to about forty years old, but then suddenly deafness strikes people with DFNA9. The cells of the inner ear can no longer reverse the damage caused by a genetic defect in their DNA.

Biobattery-powered microneedle patch can deliver drugs and procure testing samples

A pain-free, organic and biodegradable drug delivery patch may be on the horizon for home health care patients soon. Researchers from Tohoku University have developed a biobattery-powered device capable of both delivering large molecule pharmaceuticals across the skin barrier and extracting interstitial fluid for diagnostic purposes. They published their approach online on Jan. 28 in […]
