Biomaterials: Introduction to classes of materials used in medical applications: Metals, polymers, ceramics, bioresorbable and biodegradable materials, coatings, medical fibers, non fouling surfaces.

Testing of biomaterials: In Vitro and in vivo assessment of tissue compatibility. Testing of blood-materials interactions. ISO standards for testing of blood compatibility and tissue compatibility. Degradation of materials in the biological environment: Effects of the Biological environment on metals, polymers and ceramics. Relevant international standards: ISO, FDA and ASTM

Toxicology: cytotoxicity, systemic effects, genotoxicity, carcinogenicity, reproductive toxicity, sensitization & irritation, tissue comptability and inflammatory response, evaluation of host response.

Metals and ceramics: stainless steels, cobalt based alloys, titanium based alloys, characteristics and processing of bioceramics, nearly inert crystalline ceramics, porous ceramics, bioactive glasses and glass ceramics, calcium phosphate ceramics, calcium phosphate coatings, resorbable calcium phosphates, clinical applications of hydroxyapatite. Pyrolytic carbon.

Dental materials: Introduction to dental materials polymers, ceramics and metals, applications of dental materials, physico-chemical, mechanical, toxicological and in vitro clinical performance of dental materials and implants.

Polymers in drug delivery : Introduction to polymeric drug delivery systems, Targeted drug delivery. Passive or active targeting, targeting tumor cells, polymer-protein conjugates, polymer drug-conjugates. Pharmacokinetics. Application of hydrogels in controlled drug delivery systems.

Smart biomaterials: Stimuli responsive polymers (pH, temperature, light, magnetic and biomolecules) and their applications as biomaterials. Stimuli responsive hydrogels.
