29623 - Nanobiotechnology

Learning outcomes

At the end of the course the student has: - a global understanding of nano(bio)technologies; - a knowledge of the methods for the preparation of nanostructures using top-down and bottom-up approaches, with examples focused on nanoparticles and on the self-assembly of nucleic acids; - a knowledge of the tools and methodologies for the characterization of nano (bio) structures. In addition, the student acquires the skills to choose the set of techniques suitable for the characterization of nano (bio) systems of interest and to interpret the resulting data.

Characterization techniques in nanobiotechnology:

Techniques that exploit nanostructures (nanopores and (L)SPR) the characterization of biological systems. The phenomenon of plasmonic resonance: applications on nanostructures. Examples in analytics and diagnostics.TEchniques using nanopores (4 hours).

Optical and electronic microscopy in the nanoscale: The fluorescence microscope. The confocal microscope. Advanced microscopy techniques (superresolution, selective illumination). Reconstruction techniques. Principles and applications of electronic microscopy (4 hours).

Probe microscopies: principles and functioning of STM and AFM and related techniques. Nanomanipulation techniques and measurement of forces. Techniques based on AFM. (4 hours).

Readings/Bibliography

Scientific papers will be provided and class discussion will focus on them.

Dedicated textbooks are not available. Some books will be listed during lectures, to be used as a support but not required for the class. Papers and slides will be made available during lectures.

A number of web-based resources or demo software will be made available as auxiliary material.  

Teaching methods

Frontal lectures, possibly also delivered by guest researchers from other universities. When possible, small demonstrations will be performed by the teacher. Web contents and self-assessment tests will be performed during the classes. Ideally, students should have a web-enabled device of their own available during classes (the lecture all has the University wi-fi).  

Assessment methods

Oral examination.

Teaching tools

class website (on virtuale.unibo.it or other if advantageous) with outlinks and self-assessment tests. Slides presented and discussed in class and selected papers from the scientific literature.
