Microneedle Technology Promises Pain-free Insulin Injections
Researchers at ASTI Corp., a Japanese manufacturer of automotive electronics, and Hamamatsu University School of Medicine (HUSM) have co-developed a prototype microneedle system that could provide diabetics with pain-free insulin injections. It can also be used to administer vaccines.
Made of a durable and biodegradable polyglycolic acid resin, the device prototype called Medical Microneedle System can be produced in high volumes thanks to the combination of ASTI and HUSM’s microfabrication and injection moulding technologies.
The points of the microneedles measure less than 10 µm, and the needles penetrate no more than 1 mm of skin, making it possible to administer painless shots, according to the company.
