Robot ‘bugs’ that can go just about anywhere

Mar 04, 2022 (Nanowerk News) These ancient creatures can squeeze through the tiniest cracks, fit snugly into tight spaces and survive in harsh environments: There aren’t many spaces that are off-limits to an insect. That’s why researchers at the University of Pittsburgh have created tiny bug-inspired robots that can carry...

Slightly twisted 2D semiconductors display room-temperature ferroelectricity

Mar 03, 2022 (Nanowerk News) A team of researchers at The University of Manchester’s National Graphene Institute (NGI) and the National Physical Laboratory (NPL) has demonstrated that slightly twisted 2D transition metal dichalcogenides (TMDs) display room-temperature ferroelectricity. This characteristic, combined with TMDs’ outstanding optical properties, can be used to build...

Could DNA nanodevices be used to treat cancer?

Mar 03, 2022 (Nanowerk News) One of the most promising avenues in treating cancer is to restore our immune system’s ability to recognize and attack cancerous cells. A team of University of Chicago chemists and biologists developed a tiny device that can locate tumor cells and force them to reveal...

Triboelectric nanogenerator device made from recycled waste

Mar 03, 2022 (Nanowerk News) Wearable devices could soon be entirely made of recycled waste materials – and powered by human movement, thanks to a new energy-harvesting device developed at the University of Surrey (ACS Applied Materials & Interfaces, "Wearable Triboelectric Nanogenerator from Waste Materials for Autonomous Information Transmission via...

Putting stem cells on pause

Mar 03, 2022 (Nanowerk News) People are having children later than ever before. The average age of new parents in the United States has been rising for at least the past half century. But time is tough on our bodies and our reproductive systems. For instance, as animals age, our...
