The Laboratory for Algorithmic Nanoscale Self-Assemply held a workshop at Simpson College on April 21. The lab is a collaboration that includes faculty members in computer science and the biological sciences at both ISU and Simpson. The main workshop participants were nine undergraduate students at Simpson College. Dr. Jim Lathrop of ISU Computer Science conducted the workshop with the assistance of ISU Computer Science students Taylor Bergquist and Titus Klinge. Simpson Professors Lydia Sinapova, Mark Brodie, Ron Warnet, Paul Craven, and Marv Van Wyk and ISU Professors Jack Lutz and Robyn Lutz also attended. The workshop's objective was to give the Simpson students hands-on experience using the ISU Tile Assembly Simulator (ISU TAS), a tool developed by lab alumnus Matt Patitz to simulate tile self-assembly in DNA nanotechnology. By the end of the workshop all the students were creating and running tile assembly systems for fractals and other exotic structures. Ron Warnet also treated the ISU participants to images of DNA nanostructures on Simpson's Atomic Force Microscope.
