Introduction to Medical Materials and their Applications
FCH-BCT_UNAcad. year: 2017/2018
The subject is the introduction to principles and medically relevant knowledge of nanotechnology, and the chemistry of modern materials for medical application. The students are familiarized with the structural principles of organs, tissues and cells and the principles of their regulation. The biological reactions of cells and tissues to various types of material and systems built of these materials are discussed. The health risks of materials and their nanoforms are pointed out. The above mentioned is demonstrated on examples of targeted distribution of biologically active materials and their directed releasing, regenerative medicine, tissue engineering and sensors utilisable in diagnostics and medicine. The practical part and comprehensibility are stressed at the introductory level.
Learning outcomes of the course unit
The student acquires basic knowledge of modern materials and applications prepared from these materials for medicine in the nanotechnology field and their interaction with the organism and various tissues or cells. The student is capable of understanding the principle of applications of such systems, materials and technologies for medical purposes. Another study output is a simple literary recherche picked by individual students on topics covered during the lectures.
The student must already possess basic knowledge of anorganic and organic chemistry and selected parts of physical chemistry, cell biology and physiology (ideally all at the level of secondary school).
