A paper-based metamaterial (MM) device, which can potentially be utilized for quantitative analysis in biochemical sensing applications is introduced. Proof-of-concept demonstrations are accomplished by patterning micrometer-sized MM reson­ators on paper substrates and monitoring the resonance shift induced by placing different concentrations of glucose solution on the paper MM.
