Waterproof nano technology

US scientists have successfully fabricated a paper that is waterproof to a wide range of liquids that are cheaper than current waterproofing materials on the market.

This new paper not only promises to be a reusable packaging material but can also become a viable biomedical diagnostic tool.

Nanotechnology is used by Professor Dennis Hess and colleagues at the Georgia Institute of Technology to assemble paper surfaces. This process involves several steps of removing the cellulose-infiltrated surface and exposing the natural layer of waterproofing.

"After we've assembled the surface, we coated a layer of fluorocarbon that is about 100 nanometers high on the surface of the paper ," said Dennis Hess, of the Georgia Institute of Technology . As a result, we have a superior waterproof surface.

This new waterproof paper has a lot of practical applications. They are both capable of withstanding rain when used to pack goods, and can be used as a medical device if additional sensors are attached, to diagnose diseases quickly and economically. blood or urine.

"In biomedical examinations, waterproof paper can be combined with sensor materials and react with blood or body fluids," said Professor Dennis Hess . This test is very quick, easy and economical. '

Although this new type of waterproof paper can only be produced on a small scale in research laboratories, scientists believe that the production process can be replicated and bring about changes in life. as well as in the field of public health.
