Cover Story: Metal-modified montmorillonite (MMT) particles have been fabricated for the design of novel cost-effective hybrid materials that are suitable as fluorescence-based sensing platforms. The combined effect of MMT and the metallic moiety, ascribed to the aggregation-induced emission and metal-enhanced fluorescent phenomena, respectively, leads to a remarkable fluorescent enhancement. We showed that such signal amplification improves the sensitivity of fluorescent-based detection mechanisms, such as ELISA assays, and allows the direct detection of biomolecules exploiting their self-fluorescence. The versatility of the proposed hybrid materials was further demonstrated by exploring their plasmonic properties to develop liquid label-free detection systems.View this paper
