From Cradle to Oven: Diatoms at Georgia Tech August 15 2005

Kenneth Sandhage B. Mifflin Hood Professor Materials Science and Engineering Georgia Institute of Technology http://www.mse.gatech.edu/FacultyStaff/MSE_Faculty_researchbios/Sandhage/sandhage.html Dr. Ken Sandhage gave us a tour of his laboratories to better explain the research he is currently conducting on diatoms. Diatoms are microscopic, single-celled organisms (real, living creatures) that create silica shells. These shells are extremely detailed, and could be applied to a variety of nanotechnological ends (in other words, they're small enough to be useful in the building of tiny devices). Dr. Sandhage and his team raise these creatures based on the particular shell shapes they excrete (some shells shapes are more useful than others). They then swap out those silica shells with another substance. This video explains that process. Enjoy! The download speeds of the videos are 512k/second (for high speed connections—cable and DSL connections), and 38k/second (for low speed connections—particularly modems).
