ANALYTICAL TECHNIQUES FOR BIOMOLECULES - MOD.2

The teaching course of Analytical Technique for Biomolecules is a characterizing activity characterizing the Biomolecular Chemistry curriculum of the master's degree course in Chemistry and Sustainable Technologies. The course is divided into two modules (named Module 1 and Module 2), each divided into theory lessons (held in the class) and laboratory lessons. The two modules have the common goal of building broad-spectrum skills on the principles and applications of the most important advanced techniques in the bio-analytical field, in particular:
- understanding the principles underlying bio-analytical techniques;
- developing the ability to propose, set up and manage new approaches in the bio-analytical field to solve complex problems related to the qualitative and quantitative determination of chemical species of interest in real matrices;
- develop skills to obtain analytical information from experimental data, and communicate it with full awareness of the potential, limits and uncertainties associated with techniques, application methods, analytes, specific matrices and purposes;
- develop skills and adaptability in the use of software tools for the management of advanced instrumentatio, and for the processing of analytical chimistry data with a focus on automation, networking and big data.

The expected results are defined according to the specific contents of the two modules in which the Analytical Techniques for Biomolecules course is consisting of.
