New 3-D Structures Assemble with Remarkable Precision - Science Nation

The video discusses the development of self-assembling 3D nanostructures by researchers at Brown University and Johns Hopkins University. These structures can fold on their own and have potential applications in medicine, such as targeted drug delivery to minimize side effects. The design process involves flattening shapes and using algorithms to find compact forms that easily fold into 3D structures. The manufacturing process includes heating materials to create surface tension, which fuses the structures. The video highlights the revolutionary potential of nanotechnology in various fields.
