Syllabus

Course Objectives

Aim of the course is to complete the information acquired in the Bachelor about Biomaterials, allowing students to acquire an exhaustive overview of the modern materials used for biomedical applications, with particular reference to implantable devices and prostheses in the human body, taking into consideration the current processes, technologies and treatments available or in an advanced research phase aimed at improving specific properties and characteristics of biomedical devices (tissue integration, biological compatibility, mechanical performance, etc.). The phenomena of interaction between biomaterials and the human body will also be analyzed, about the causes of possible failures of the material in operation, adverse reactions, the mechanisms of degradation of biomaterials and the reciprocal effect of the biological environment on the biomaterial/device.

Course Prerequisites

Base knowledge of chemistry and science and technology of materials

Teaching Methods

Frontal lessons, laboratory exercises and didactic visits


Assessment Methods

Written exam focused on 30 closed questions with a choice of 4 answers. The score is 1 point on request. Only by passing the written exam will the oral exam be accessed. At the end of the writing the results (in 30simi) will be displayed on the web page of the course with the calendar of the oral interviews. Students who have obtained at least 18/30 in the written test will be admitted to the oral exam. The oral examination will be a presentation on an item of the course.
