After years of work, persistence, and belief in an idea that once felt impossible, we’re excited to share our concept; an approach that we believe can shift the paradigm of multiphoton microscopy.

🔬✨¿Sabías que en #Huelva se está diseñando el futuro de la medicina?
Científicos de la (@UniHuelva) han dado con la clave para "ver mejor" el interior de nuestras células. Su técnica es tan revolucionaria que la propia revista @Nature se ha hecho eco. huelvai.info/rpb132
Exciting day in Gothenburg! Our teams are all together celebrating this year’s annual project meeting.
@LabPischel @HofkensLab
Our representatives from GU, @LabPischel, and Chalmers are these days at CECP2026 in Bad Hofgastein (Austria). Lots of great science going on in such a privileged atmosphere!

About to close this very hard year, although marked by many important milestones. 2026 can only be better💪. I can already envisage many important changes. Deeply grateful to all those who have supported and helped us🙏.
Here is our short summary from 2025. Happy New Year!

We love photoswitches, and that is a fact 🙃
Our latest work arrived just in time for Christmas and is now out in @ChemicalScience: doi.org/10.1039/d5sc08074f. Enjoy the read!

After about 20 months (😱!) of peer review process, our paper on DTE photoswitches is finally out in the @angew_chem journal 💪😀 The general kinetic model of ring opening and closing reactions is presented.
