Small and sensitive
The lab itself is just visible to the naked eye; many of the components are the same width as one of your hairs. The sample taken from your body travels down tiny channels where nano-sized components and sensors identify the specific molecules that might warn of illness.
Scientists are trying to make these mini labs even smaller so they will be even faster and more sensitive.
