Biotagging method for animal identification using dissolvable microneedle arrays prepared by customisable moulds
While it's important for your dog or cat to have a form of ID in case they get lost, tags can fall off, and microchips can migrate out of place. Japanese scientists are developing an alternative, in the form of quick and painless tattoos.
In most cases, these devices take the form of a small, flat piece of material with an array of tiny, sharp, medication-filled studs – or "microneedles" – on its underside.
