Course detail

Polymers for medical applications

FCH-MCO_PMAAcad. year: 2019/2020

Polymers are an important part of the biomaterial used in medicine, especially as parts of medical devices, biosensors, implants, drug or cell carriers. The subject summarizes the current knowledge about the synthesis of biomedical polymers, including their modification, copolymerization, functionalization, Self-organizing processes and characterization. Emphasis is placed on the properties of hydrogels and biodegradable polymers usable in medicine, with a view to testing their biocompatibility, stability and bioactivity in living organisms. Part of it is devoted to methods of preparing scaffolds for tissue engineering and biomaterials for bone, replacement overview, tendons, cartilage, skin, nervous and cardiovascular systems. The subject deals also in a composite polymer material containing (nano) fibers or (nano) particles, their properties and applications in medicine.

Aims

The course will provide students with basic knowledge of polymer materials usable for applications in medicine, their history and the present. Apart from commercially available materials, students will be especially familiar with (bio) polymer materials in the research stage, with their synthesis, sample preparation, characterization and testing in vitro and in vivo, focusing on individual medical applications, especially for tissue engineering.
