• efficiency could be observed, while other modes are inundated by noise. The high-order modes have close eigenwavelengths, resulting in the resonance shift in Figure 4c. Theoretically, all modes could be captured in the spectrum, but the excitation and collection efficiency cannot simultaneously reach maximum

Sensing of chiral molecules As a proof of concept, the sensing power of the honeycomb ECMs were investigated by monitoring the resonance shift upon adsorption of the chiral organic molecule cysteamine and

• shifts compared to the bare structure are summarized in Table 1. A similar plasmonic resonance shift of the resonance mode around 770 nm upon adsorption of cytochrome c was observed at different θ angles (Figure 12 and Table 2). This indicates that the sensitivity of the plasmonic resonance towards
