CHINA: According to research, human tears can now detect eye diseases including diabetes.
We used to think that human tears were just what they seemed, but because of recent advances in technology, we now know that they hold a plethora of data.
Human tears may now detect eye disease and even early signs of diabetes, according to researchers who report their findings in the journal ACS Nano on July 20.
Fei Liu, a biomedical engineer at Wenzhou Medical University, said, “We wanted to demonstrate the potential of using tears to identify the illness.”
Similar to saliva and urine, tears also contain tiny sacs that are jam-packed with cellular impulses. If scientists could intercept these tiny mailbags, they might provide new information about the body.
To acquire data, the team adopted a fresh strategy. They started by gathering the tears of the research participants.
The researchers then applied a regular solution to two nanoporous membranes in a device, vibrated the membranes, and forced the fluid through.
The procedure keeps the sacs behind for analysis while allowing small molecules to escape in a matter of minutes.
The results provided scientists with a new perspective. Researchers found that different types of dry eye disease each leave distinct molecular traces in people’s tears.
Now we must find out what else human tears can do.
