Biosensors based on nanocomposite materials: Synthesis of nanocomposite polymers / nanostructured materials structures; characteristics and applications in the field of sensors.
Prerequisites
We recommend that you have taken the following first-year exams:
Physical-Chemistry and Biochemistry, which represent the basis for understanding the Course topics.
Books
A specific text is not required, articles will be provided to deepen the topics covered as well as it will be possible to download the complete slides of the lessons on the teacher's website.
Teaching mode
The Course consists of 32 hours of frontal lessons with the students. The lessons are all interactive, so the teacher stimulates the students with questions to which they, by virtue of the courses already followed, and the progress of the course can give an answer. This allows the teacher to make evident the links between the current course and some previous courses, whose notions play an important role in understanding what is proposed in class. The continuous references to notions of previous courses but also to those that will be followed in the following years, have the purpose of accustoming the student to consider the proposed subject not as something closed, aimed at passing the final exam, but wants to educate the student to a multidisciplinary study, which is absolutely required for a student of this degree program. The student will find on the e-learning platform the slides and the teaching material useful for the preparation of the exam. It is understood that the slides are a guide to the exam topics, but they can never absolutely replace the lectures given by the teacher.
Frequency
Attendance at the course is optional but recommended.
Exam mode
The assessment methods of the course are characterized by an oral exam call fixed each month of the year, excluding the months of August and December. The exam is open for 15-20 days to give students the opportunity to choose the most appropriate date to take the exam. The vote is expressed in thirtieths, with possible praise. Passing the exam presupposes the conferment of a grade of not less than eighteen / thirty and involves the assignment of the corresponding university credits. In the evaluation of the tests for the purpose of the assignment of the final grade, the following will be taken into account: the level of knowledge of the demonstrated contents (superficial, appropriate, precise and complete, complete and in-depth), the ability to apply the theoretical concepts (errors in applying the concepts, discrete, good, well established), the capacity for analysis, synthesis and interdisciplinary links (sufficient, good, excellent), the capacity for critical sense and the formulation of judgments (sufficient, good, excellent), the mastery of expression (deficient, simple, clear and correct, safe and correct). In general, we start from very general questions about the main concepts of the Course followed by more specific and more detailed questions about the application of the principles studied to describe real phenomena. To pass the exam, the mnemonic study is not recommended, but the understanding of the main concepts is required in a preponderant manner. At the end of the course, scientific papers will be provided on the various topics of the topic that will be the basis for discussion of the exam. In general, it starts from very general questions on the main concepts on biosensors and nanotechnologies followed by more specific in-depth questions of increasing complexity concerning the application of the principles studied to describe real phenomena. The ability to connect and compare the topics held in different parts of the course and/or in other courses is particularly appreciated. Numerical examples may also be processed during the test.
