Professoressa Associata





Sara Bonacchi obtained her MSc degree in Chemistry at the University of Firenze (Italy) in 2005 and then, she moved to the Photochemical Nanosciences Laboratory at University of Bologna (Italy), where she obtained her PhD in 2009 under the supervision of Professor Luca Prodi.
In her first postdoc, she engineered new platforms for sensing and bio-imaging applications based on novel nanostructures as core-shell/silica-PEG and metal nanoparticles. In particular, she studied the morphological and photophysical properties of fluorescent labels and sensors based on dye-doped nanoparticles.
In 2013, she moved to 'Institute de Science et d'Ingéniere Supramoléculaires, I.S.I.S.' - Nanochemistry lab (Professor Paolo Samorì) at University of Strasbourg (France) where she was involved in 'Self-Assembled in Confined Space, SACS' European project. In 2014, she was awarded Marie Curie Intra-European Fellow (IEF) for a research project on tuning the electrical and optical properties of monolayer graphene/2D materials-hybrid systems via self-assembled of light switchable molecules.
She is now a non-tenured assistant professor (RTD-a) at the Department of Chemistry – University of Padova (Italy) where she is the Principal Investigator of the ‘Ultrasmall Chiral Gold Nanoclusters for Asymmetric Redox Catalysis” CARIPARO Starting Grant Project in Molecular Electrochemistry and Nanosystems Group.

Scientific Output
She is Co-author of 44 papers in peer-reviewed journals and 4 book chapters, co-inventor of 5 international patents. Regular dissemination in international conferences in seminars, posters and lectures. H-index = 22, and 906 citations (without self-citations, source database Web of Knowledge, January 2018).
