Smart nanotissues can change color due to temperature, presence of viruses or for camouflage

Imagine a cleaning pad that can detect the presence of bacteria or pathogens and change

color to another, or an N95 respirator mask that can detect the presence of a new coronavirus and respond in a way that alerts the user.

For their work, Tang and his group usedan electric spinning wheel, which in its functionality resembles an automatic machine for the production of cotton candy. The nozzle generates material, which is then drawn into fiber and rolled into sheets.

Polymer nanomaterials are made fromplastics such as nylon or polyethylene. Same material as plastic soda bottles. Tang Lab produces non-woven nanofibers similar to reusable shopping bags that can be easily mass produced.

These “smart fabrics” are made from soft, lightweight andelastic materials and can be used in clothing, for example, for disguise, or for other purposes, for example, to detect the presence of a pathogen. They have also been used to create wearable sensors and devices.

In the case of the N95 mask, according to scientists, the ownerwill know "when to change it, instead of just guessing the safe period." With cleaning wipes, "you can keep wiping until they stop changing color."
