3D printed breathalyzer
A 3D printed breathalyzer that costs as little as $29 to make
has been used to “sniff out” 17 different diseases, including Parkinson’s and
eight types of cancer. The device uses gold nano particles that react to certain
exhaled chemicals, and is claimed to be 86% accurate.
Scientists used a 3D printed breathalyzer to diagnose 1,400
patients from across the world
It certainly seems unscientific when compared to other
medical procedures, but smelling a patient’s breath has been an effective form
of diagnosis since Ancient Greek times, when famed physician Hippocrates
practiced the procedure to determine his patients’ illnesses. Back then,
doctors would even go so far as to sniff a patient’s urine or taste their
sweat.
