Introduction to Biomaterials


The main goal of the course is to give an insight to materials structure-properties relationship, with enphasis on materials for biomedical applications.

Teaching method

Two tipes of presencial classes: Lectures (2h/week); Practical (2 h/week). Lectures will be supported by powerpoint slides.

Tuturial classes are also available every week (2 h/week) for supporting the students in there homework.

Evaluation method

Evaluation has 5 components:

1 - Individual Quiz Test concerning Lab activitiy (MTL);
2 - Report (RAL) of lab activity (group activity);
3 - Individual quiz tests on T and TP classes (Q) ;
4 - Research activities / selected exercices (P)
5 - 2 Tests (T) or a Final Exam (EF) covering lecture topics. 

Final grade is obtained by:

i) 0,05*MTL+0,10*RAL+0,15*Q+0,10*P+0,60*(average T);


ii) 0,05*MTL+0,10*RAL+0,15*Q+0,10*P+0,60*EF

If the teacher finds necessary, students with a final grade equal or higher than 17 will be subjected to oral examination.

Subject matter

Theorectical topics:

1. Materials classificatiion. Biomaterials and biocompatibility.

2. Metalic and Ceramic materials: Crystal structure and crystal geometry; X-ray diffraction; Crystalline imperfections.

5. Phase diagrams.

4. Polymeric Materials.

5. Mechanical properties of materials

6. Linear Viscoelasticity.

7. Rubber elasticity.

8. Elasticity of biological tissues: the formation of an aneurysm - analogy with rubber elasticity.

Lab classes:

1 - Synthesis of PMMA and Nylon 6-10

2 - Tensile tests of a metal and a polymer: Analysis of the stress-strain curve.

3 - Rubber elasticity (Gough-Joule effect, uniaxial and biaxial tensile tests).
