Eggshell membrane as a multimodal solid state platform for generating fluorescent metal nanoclusters

Eggshell membrane (ESM) has been employed as a unique and especially efficient synthetic platform capable of generating fluorescent silver and gold nanoclusters via various chemical routes. Potential applications of the metal/ESM adducts include recyclable catalysts, sensing paper, surface enhanced Raman scattering interface, fluorescent surface patterning and anti-counterfeiting.
