1 nm‐Resolution Sorting of Sub‐10 nm Nanoparticles Using a Dielectric Metasurface with Toroidal Responses

Optofluidic Sorting In article number 2300100, Xiang Fang, Yuzhi Shi, Xinbin Cheng, and co-workers achieve 1 nm-precision sorting of sub-10 nm polystyrene nanoparticles 3 exsomes by exploiting the electromagnetic toroidal dipole multipoles in a dielectric metasurface. Medium-sized can be screened out from mixture different gold sorted with photonic slot.
