Silicon micro-needles deliver painless injections

Painful vaccinations will become a thing of the past thanks to a clever new invention from Swiss medical device maker Debiotech. The company is working with Leti to develop a process for making silicon micro-needles that are only 700 microns long, preventing the needle from reaching the nerves in the dermis while boosting injection efficacy; for certain vaccines the necessary dosage could be cut by a factor of five.
Based on a prototype provided by Debiotech, Leti scientists designed a 200-mm deep etching process, which has already achieved record yields, marking yet another successful collaboration under Leti’s 3S technological innovation offering (see MINA-News 18).
