Many people around the world do not have proper medical care because proper treatment is expensive.
Blood tests are the traditional way to test for diseases, but a new invention uses urine and does not require a pricey lab.
Chemist Hong Liu and Richard Crooks have invented a device that can instantly detect diseases.
It called oPAD (Origami Paper Analytical Device) which is made from paper and is extremely cheap.
To make the process less complicated, Hong and Richard believed that Origami was the solution.
The paper contains chemicals that will react to a person's bodily fluid.
It turns a different color to indicate that the patient has a disease.
You can even add a small battery to the oPAD for the tests that require power.
This invention could change our world and save the lives of thousands!
