The main program is presented in the following clear-cut sections: What is nanotechnology?; Units: micrometer and nanometer; Special properties of nanoparticles; The gecko effect; Carbon nanotubes; Surface energy; hydrophilic and hydrophobic surfaces; The lotus effect; Use of lasers in nanotechnology; Issues raised by nanotechnology. Because nanotechnology works with the metric units nanometer and micrometer, this program uses metric units. However, this should not affect a student's understanding of the concepts presented in the program.
