a Scanning electron microscope (SEM) images of a nanostructured Lycurgus cup array and gold nanoparticles. Scale bar in the figure indicates 0.5 μm. b Transmission spectral sensing of biotin–streptavidin binding on the nanostructured Lycurgus cup with/without gold nanoparticles. The resonance dip did not change in the 100 ng/mL biotin-streptavidin binding on the nano-Lycurgus cup without gold nanoparticles, but a spectral shift of 4.9 nm was detected on the nano-Lycurgus cup with gold nanoparticles. The re-print of this figure from [138] is permitted by Wiley
