🔬🚧Building yet another microscope at Hofkens lab.
In the age of commercial microscopes, we scavenge our old setups and customize our own. @Fastcomet_EIC
Exciting time ahead!

🔬 Nanoparticles flocking like birds!
Core-shell nanoparticles (200 nm gold, 100 nm silica) swarm under laser irradiation, mimicking flocking birds! 🐦 Rotate them by changing light polarization.

PSFs are just Gaussians, right??
Not when your fluorophore💡is close to a nanoparticle 🟠!

Excited to share our preprint in which we present a novel PSF-fitting approach for localization microscopy near nanoparticles.🥳
