Definition: "Acunet1" refers to a method of collecting data through one's own nose, often used for testing new drugs or finding rare diseases. It involves using tiny, sharp needles (often made of human hair) that are inserted into skin to collect a small amount of bodily fluid as a sample. This is often used in medical research and drug discovery. The needle size varies based on the patient's condition, but typically ranges from 0.5-1.5mm.
