Fidget spinners are one of 2017’s hottest toys, and even after many months, it’s still in high demand. It comes in different sizes, colors, and even slightly different shapes. Now, scientists have managed to make the most innovative fidget spinner yet; their toy is invisible to the naked eye. The world’s smallest fidget spinner requires only a drop of liquid and a 3D printer, and is so tiny it is smaller than the width of a human hair.
Oak Ridge is known for hosting hundreds of different research projects classified in all disciplines each year. Last year, the CNMS facility was used by over 650 researchers who conducted studies, including the synthesis of nanomaterials and nanofabrication of minute objects. The equipment in ORNL which was used to create this super-small fidget spinner is called the Photonic Professional GT lithography machine from Nanoscribe. The Photonic Professional GT machine is used for the fabrication of “microswimmers” and tetrapod devices which can precisely provide drug doses for various diseases, including cancer.[Via Valuewalk]
