I don't know if Gorillas work the same way as dogs, but maybe you could put something that smells nice on a device that extends a small nose-boop extractor arm when close, and gather the noseprint that way. To simulate this invention: - have a dog - put something smelly on your thumb - extend arm to point thumb towards dog - as the dog is within 5-10cm radius of your thumb, press your thumb against their nose (and say the obligatory "boop") - imagine your had something to extract noseprints from their nose on your thumb
