Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

Laser &Photonics Reviews, EarlyView.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.
