Summary
Student is acquainted with the issue of nanomachines - a relatively new and increasingly evolving area of nanotechnology. An unconventional view of molecular and supramolecular structures is presented in terms of their properties and functionality, and the knowledge of students in chemistry and physics of nanomaterials is further extended to understand the principles of nanomachines and the methods of controlling their intended motion. Wide range of nanomachines, from simple synthetic functional components to complex nanomachines based on synthetic and natural supramolecular structures is presented in this course. The first practical applications of the nanomachines are also discussed. The seminar is supplemented by many examples from the scientific literature.
