Nanotechnology for biomedical applications and biosensors
A.A. 2023/2024
Obiettivi formativi
Incorporation of functionalised and modified nanostructures in various biomedical applications has generated considerable research interest in recent years. The applications of nanotechnology in medicine and biomedical engineering are vast and spans areas such as implant and tissue engineering, diagnosis and therapy.
This course is intended to provide the student with a general background in the field of nanotechnology applied to biological systems and biomedical applications. In particular, during the course different typologies of nanoparticles will be described focusing on their employment as drug delivery systems, diagnostic probes and sensors for the study of biological interactions.
The course is ideally linked to those dealing with chemistry and materials science.

Programma
Lectures by Prof. Valentina Pifferi (3 CFU) will first focus on sensors for biomedical applications: definition of sensor and biosensor, similarities and differences, their applications and their classification. Lectures will then describe the features of a good sensor, the biological components and their immobilization systems. The last part will focus on different types of transduction systems: electrochemical transducers (potentiometric, amperometric, voltammetric and conductimetric transducers); FET (IGFET, CHEMFET, ISFET, ENFET); optical transducers; piezoelectric transducers; thermal transducers. Applications to real cases will be discussed.
Lectures by Dr. Laura Polito (3 CFU) will first provide a general introduction about bio-nanotechnology: (i) advantages of the use of nanoparticles (NPs) in biomedical applications (sensors for the study of biological interactions; drug delivery systems, contrast media for diagnostic techniques); (ii) influence of the materials employed for NPs fabrication as well as of their physico-chemical properties (size, shape, surface charge, etc) in biological interactions; (iii) general approaches for surface functionalization; (iv) passive and active targeting.
Lectures will then describe different typologies of nanoparticles based on organic material (i.e. liposomes) or on inorganic material (i.e. iron oxide NPs, gold NPs). General characteristics, physico-chemical properties, methods of fabrication and functionalization will be described for each type of NPs, together with examples of applications.
