We experimentally demonstrate the integration of a microfluidic trap array on top of
metamaterial resonators for size selective trapping and remote sensing of microparticles. A
split-ring resonator (SRR) design supports strongly confined electric field in the capacitive
split gap at the fundamental inductive-capacitive resonance mode. The tightly confined
electric field in the SRR gap forms a hot-spot that has become an enabling platform for
sensing applications. Here, we extend the concept of metamaterial sensing to “trapping and …
