Bioimaging
A.A. 2024/2025
Obiettivi formativi
The imaging of biological samples, or bioimaging, plays a key role in current life science research, enabling scientists to analyze molecules, cells and tissues from a range of living systems. Developments in microscopy techniques and associated tools now allow imaging across an extensive range of scales, from 1-2 nm to whole organism phenotyping.
The aim of the course is to present the theory and the practice of different techniques of microscopy (optical, electronic and scanning probe) also applied in lab-on-a-chip systems.
The course is ideally linked to those dealing with the need of imaging, i.e. molecular and cellular biology, etc.

Programma
Part 1
The first part of the course provides a description of the imaging techniques applied to biology. Some basic notions of geometrical optics are functional to the detailed description of optical microscopes. Confocal microscopy and related techniques (FRAP, FRET, FLIM) will be extensively treated together with more recent developments in super-resolution techniques, in particular SIM, PALM, STORM, STED. Electron microscopies (SEM, TEM, Cryo-TEM) will be presented underlying the different investigations on biological samples that can be carried out. Atomic Force Microscopy (AFM) will be also presented as a versatile approach for measuring mechanical properties of biological samples.
Part 2
The second part of the course deals with the topic of in vitro quantitative cell and tissue biology.
An overview of physic laws governing small systems will be highlighted and explained through Lab-on-chip (LOC) devices, that are laboratory functionalities integrated into miniaturized devices. Next, biomaterials commonly employed as scaffolds in tissue engineering and the related fabrication technologies (focusing on 3D bioprinting) will be presented together with those methodologies used to modify their chemical surface properties. In the end, some examples of engineered 3D cell cultures will be deeply discussed and practical problems will be presented.
