Self-Folding Straw Wicks Liquids Automatically

Jun-28-16 A plant-inspired material that forms a tube to deliver liquid could offer a safer way for researchers to manipulate toxic chemicals.

Developed by a team from the Australian National University, the material is made up of two nanofiber layers. The top layer is superhydrophilic, and will curl automatically to form a tube around a drop of liquid. The bottom layer is superhydrophobic, and will keep the water in the tube as a sort of waterproof liner as the water moves through the material.

The team believes the material could be used to control the flow of liquids in areas that could be hazardous to humans, such a bio-sensors of infectious diseases.
