Nanotechnology

• Biomedical Engineering, Semester 3, position 1

Goal of this subject is for students to acquire knowledges of: electron tunnelling phenomena, molecular atractve and repulsive forces, nanomaterials, conversion and transport of energy on nanoscale level. Introduction of basic methodes, techniques and devices for characterisation of nanomaterials: Scanning NanoProbe microscopy and spectroscopy. Nano electrochemical cell. Characterisation of conductive, magnetic and non-conductive materials: inorganice as well as biological. Nano films: characterisation and modification of sample surfaces by STM/AFM/MFM methodes.

Upon successful completion of this course, students will be able to: •Distinguish between the basic components and principles of electron tunneling as well as the basic components and principles of attraction-repulsion effects •Apply basic theoretical and experimental knowledge to analyze nano system •Work on devices for characterization of nanomaterials, STM and AFM •Carry out appropriate preparation of various samples for the scanning probe microscopy •Performs characterization of materials at the nano level •Apply acquired knowledge of software analysis of graphical and analytical data obtained by scanning probe microscopy
