Leveraging Partial Coherence to Enhance Nanoparticle Detection Sensitivity and Throughput in Interferometric Scattering Microscopy Interferometric-based microscopies stand as powerful label-free approaches for monitoring and characterizing chemical reactions and heterogeneous nanoparticle systems in real time with single-particle...

🚨New paper alert!🚨 We show how tuning partial coherence in reflection iSCAT boosts single nanoparticle + protein detection.

Big congrats to PhD student Chiara for leading this

Wide-field spectroscopic imaging of optical activity - Nature Photonics A wide-field microscope capable of simultaneously measuring circular dichroism and circular birefringence signals over wide fields of view of the order of hundreds of micrometres is demonstrated, addr...

Can polarization-sensitive digital holography contribute to wide-field spectroscopic imaging of chiral samples? We answer this question in this new article! Big congrats to Rebecca Büchner, PhD student leading the project!

Our microfluidics expert just macro-graduated! 🎓💧 Congratulations, Dr. Sulliger.🎉

Is solid matter always attracted by light intensity maxima? We challenge this well-established principle by demonstrating a novel regime wherein the sign of the force exerted on a suspended metasurface is precisely controlled. Congrats to the team! arxiv.org/abs/2504.18341
