Sorting Gold and Sand (Silica) Using Atomic Force Microscope-Based Dielectrophoresis

Abstract Additive manufacturing–also known as 3D printing–has attracted much attention in recent years as a powerful method for the simple and versatile fabrication of complicated three-dimensional structures. However, the current technology still exhibits a limitation in realizing the selective dep...
