Prof. Serena Arnaboldi is a faculty member at the University of Milan, where she also obtained her PhD in 2015. She has continued her scientific journey by spending time in various laboratories in Italy (Rome, Genoa) and abroad at the Institute of Polymer Chemistry in Stuttgart, Germany, and the University of Bordeaux in France. In 2022, she was appointed Associate Professor of Analytical Chemistry at the University of Milan, where she leads her research group. Her scientific interests focus on electrochemistry, particularly chiral electroanalysis. She publishes in renowned scientific journals such as Chemical Science, Angewandte Chemie, and Nature Chemistry. She is also the recipient of an ERC Starting Grant.

In nature, charge recombination in photosystems is minimised by efficient charge separation across the thylakoid membrane. In a semi-artificial photosynthetic approach, we aim to mimic this principle by coupling light-harvesting or photocatalytic nanoparticles (NPs) to lipid vesicles. Key to this approach has been an icosahaem membrane protein, MtrCAB from Shewanella oneidensis MR-1. In this protein, twenty haems form a ~15 nm long molecular wire, which efficiently transfer electrons across lipid membranes. Interaction and photo-induced electron transfer between light-harvesting NPs and MtrCAB is studied, among others, with life-time fluorescence, X-ray footprinting mass spectrometry and photoelectrochemistry. Transmembrane photoreduction is observed in liposomes loaded with redox-active dyes. Finally, by encapsulating biocatalysts like hydrogenase in the liposomes, a compartmentalized biohybrid photocatalytic system has been realised. We envision that these approaches can ultimately be used to develop whole-cell biophotocatalysis in the future.
Short CV
After studying Biology in Utrecht, Lars Jeuken started his PhD studies in 1995 in Leiden on the structure-function relationship of copper proteins. After a Post-Doc in Oxford (1999-2002), where he learned bioelectrochemistry, he was awarded a BBSRC David Phillips fellowship, which he took to Leeds to study respiratory membrane enzymes with electrochemistry. In Leeds, he received an ERC consolidator grant and became professor in 2017 while studying novel hybrid nanoparticle-biocatalytic system for solar fuel production. In 2021, he moved to Leiden where he continues his research.
