Week 8: Nanotechnology + Art
The materials that most interested me this week were Dr. James K. Gimzewski’s YouTube videos entitled Nanotechnology for artists (1). My favorite part was the images shown below of shapes made by Don Eigler using Scanning Tunneling Microscopy which uses a needle whose tip measures about one hundredth of an atomic diameter. The needle rasters across surfaces to make images, in a similar process to the one used in a cathode ray tube, the original type of television (2). Patterns created using the Scanning Tunnel Microscope Even more powerful is the Atomic Force Microscope which is able to image molecules in a way that hadn’t been achieved before with the Scanning Tunnel Microscope (2). Today there are thousands of nanotechnology products on the market and many of them are invisible. Atomic Force Microscopy Nanoparticles are sized between 100 and 1 nanometers, and they have existed for a long time. In Roman times they were used to make pottery out of gold that looks one c...
