The 12th International Weber Symposium on Innovative Fluorescence Methodologies in Biochemistry and Medicine was held in Genoa, Italy from June 15-20, 2025.

The “Weber Symposium” honors the fundamental and far-reaching contributions of Professor Gregorio Weber. It provides an overview of modern fluorescence methodologies and applications in the biological and medical sciences. Weber symposia were held in Búzios, Brazil, in 2017, in Hawaii in 2014, 2011, 2008, 2005, 2002, 1999, and 1995, in Italy in 1986 and 1991, and in Uruguay in 2023.

Speakers describe state-of-the-art and emerging technologies used in their research programs. Topics include time-resolved fluorescence, phasors, Förster resonance energy transfer, multi-photon fluorescence microscopy, confocal microscopy, single molecule studies, fluctuation correlation spectroscopy, fluorescence imaging spectroscopy, macromolecular (nucleic acids and proteins) interactions, membrane dynamics, and quantitative cellular dynamics including metabolism.

We are extremely grateful to all the organizers for inviting us to participate of this wonderful meeting. Special thanks to (the great) Prof. David Jameson, Prof. Leonel Malacrida and Prof. Alberto Diaspro.
