Learning Objectives

The objective of this course is to introduce the basic principles and techniques of modern analytical chemistry necessary for the structural characterization, qualitative-quantitative analysis and optimization of the production processes of biotechnological drugs.
At the end of the course the student: - acquires the basic notions for the structural characterization of biotechnological drugs using spectroscopic and spectrometric techniques; - acquires theoretical knowledge of chromatographic separations and capillary electrophoresis for the analysis of biotechnological drugs; - acquires the strategies for the development of new instrumental methods for the qualitative and quantitative identification of biotechnological drugs in pre-clinical / clinical research and in quality control; - acquires knowledge for sample preparation; - acquires knowledge for the validation of analytical methods according to current guidelines.

EXPECTED RESULTS
Knowledge and understanding: the student will have to acquire the theoretical and practical preparation for the analysis and structural characterization of biotechnological drugs reported in the official pharmacopoeias, using instrumental analytical techniques.
Ability to apply knowledge and understanding: the student must be able to use the knowledge acquired in the field of instrumental analysis to design, develop and validate protocols for the analysis of biotenological drugs in complex matrices.
Autonomy of judgment: The student must be able to interpret the experimental results obtained.
Communication skills: At the end of the course, the student must be able to explain what he has learned using an adequate terminology for a correct scientific presentation regarding the analytical techniques for the characterization of biotenological drugs.
Learning ability: The student must have developed theoretical/practical skills useful to be able to update his knoledge in order to face new analytical problems.


Course Structure

Theoretical classroom lessons (42 hours) with the aid of video projection systems of slides and videos.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning assessment may also be carried out on line, should the conditions require it.
