New fluid-repellent paper could lead to inexpensive diagnostic devices

New fluid-repellent paper could lead to inexpensive diagnostic devices | Longevity science | Scoop.it

Scientists at the Georgia Institute of Technology have produced a new kind of paper that repels a range of liquids, including water and oil. The new paper shows significant promise as an affordable and recyclable packaging material, but it's the paper’s potential as an inexpensive biomedical diagnostic tool that has really got the researchers excited.

 

By applying a chemical coating and creating new surface patterns at the nanometer and micron-scale, the researchers are able to reproduce the same repellent effect in the paper that is observed in the leaves of the lotus plant. This changes the paper from an absorbent material to one which repels all fluids.
