The Polyanalysis Forum 2026, organized in collaboration with Prof. Haritz Sardon (POLYMAT) and Tosoh Bioscience, was held on May 21, 2026, at the Centro Carlos Santamaría in San Sebastian, Spain. The symposium gathered experts from academia and industry for a full-day event dedicated to polymer analysis, with a central spotlight on precision polymer synthesis.

Through his role as an organizer, Haritz Sardon helped assemble an international panel of researchers to discuss recent advances in polymer design and characterization. The scientific programme featured a series of specialized presentations covering diverse technical challenges and methodologies:

Holger Frey (Johannes Gutenberg-Universität) discussed how structural isomers of Poly(ethylene glycol) (rPEG) offer new perspectives for biomedical applications.

Christopher Barner-Kowollik (Karlsruhe Institute of Technology) presented insights into "The Precision Photochemistry Paradigm."

Frank Leibfarth (University of North Carolina at Chapel Hill) addressed the selective post-polymerization C-H functionalization of polyolefins.

Marta Ximenis (University of the Basque Country) presented on the spatiotemporal regulation of dynamic networks using photo- and thermo-responsive switches.

Fabienne Barroso (Donostia International Physics Center) detailed the synthesis of cyclic polymers assisted by Gel Permeation Chromatography (GPC).

Snežana Đorđević (Tosoh Bioscience) shared analytical lessons from diverse polymer systems using GPC‑MALS.

In addition to the main speaker sessions, the forum provided a platform for early-career scientists. PhD students and postdoctoral researchers had the opportunity to highlight their ongoing research through a series of flash presentations, complemented by a dedicated poster session. This poster session allowed attendees to dive deeper into the technical details of emerging projects, while the structured networking breaks further facilitated knowledge exchange and fostered new collaborations within the international polymer science community.
