What do the freezing process and the 2022 Nobel Prize in Chemistry have to do with the functionalization of nanoparticles ... and why would it matter? Check out our latest work out in @J_A_C_S tinyurl.com/mr27z9j6 in collaboration with @HiroshiSug61443 and Denis Garoli. 1/4

It was great to meet @HiroshiSug61443, our longtime collaborator on all things silicon. 🎉

He gave an informal talk, and we also had the chance to share our work with him.

Always inspiring to exchange ideas and catch up in person!

💡 New paper alert!

Metallic nanoparticles (NPs) have long been used for enhanced spectroscopies, sensing & imaging due to their unmatched electric field enhancements.

But there's a catch:
- Fluorophores near metals often quench
- Metals suffer from ohmic losses

Alternatives?

Many thanks to @ssimoncelli and the whole team for this excellent work!

In this collaborative effort, we show a powerful tool for imaging complex biological systems and push super-resolution imaging to new limits and achieve sub-10 nm precision across large FOVs

Last week, Prof. Fernando Stefani (@FernaStefani) gave a course on Advanced Optical Imaging. He covered topics in super-resolution imaging - in other words - how to use diffraction limited light sopts, to get sub-diffraction imaging!
