Nanotechnology for biomedical applications and biosensors
A.A. 2020/2021
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.

Teaching methods
The lessons will be held on the Microsoft Teams platform and can be followed both synchronously based on the timetable of the first semester and asynchronously as they will be recorded and uploaded on that same platform.
Course syllabus and Teaching Resources
The contents and reference material will not be changed; moreover recorded lessons will be made available.
Assessment methods and Criteria
The final exam will be an oral test through the Microsoft Teams platform or, if so permitted by regulation, in person.

Programma
Lectures by Dr. Daniela Meroni will focus on sensors for biomedical applications: definition of sensor and biosensor, similarities and differences, applications of sensors and biosensors, their classification. Features of a good sensor. Biological components and their immobilization systems. 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
Lectures by Dr. Daniela Arosio 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 both based on organic material (liposomes, polymeric NPs, polymeric micelles, polymersomes, dendrimers, polymer/lipid-DNA complexes i.e. "polyplexes"/"lipoplexes" , etc) and on inorganic material (iron oxide magnetic NPs, gold NPs, mesoporous silica NPs, etc). General characteristics, physico-chemical properties, methods of fabrication and functionalization will be described for each type of NPs, together with examples of applications.

Modalità di verifica dell’apprendimento e criteri di valutazione
The evaluation of the student's performance will be based on an oral exam with open questions on subjects covered during the course. For students attending the course, two "in itinere" partial exams are planned.
The mark is provided on a 30-points scale. In the case of partial exams, the final mark is the average of the scores obtained in the two parts.
