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.

Subject syllabus:

1. After an initial introduction to the history and the current state of nanomachine research, various definitions of the term \"nanomachine\" and basic classification is presented. Differences and similarities of machines and nanomachines are discussed. In relation to supramolecular nanomachines, the basics of supramolecular chemistry are presented. 2. The methods of motion/function monitoring and visualization of nanomachines are presented. Attention is paid to rotational and conformational changes, followed by methods of propulsion - self-propelled vs. externally controlled nanomachines. Students get acquainted with the problematics of nanomachine motion in liquid. 3. Attention is paid to coordination chemistry, coordinate covalent binding and its description. Different types of coordination complexes are presented and their stability is discussed. In addition to complexes, attention is also paid to other compounds useful in the synthesis of nanomachines. 4. Various types of molecular functional units are presented with particular focus on molecular rotors and molecular brakes. Factors influencing the rotation speed, the problem of continuous rotation and the effectiveness of the braking elements are discussed. 5. Based on the previous topic, the nanovehicles are presented. Various types and methods of controlling their movement is introduced. Problems of synthesis efficiency and manipulation with nanomachines are demonstrated on the example of these nanomachines. 6.
