Fig. 1. Schematic illustration showing (a) the synthesis of Ru–PEI@SiO2 HLNs and (b) fabrication of a flexible MIP-ECL sensor for the epidermal analyte detection. (i) Galvanic conversion of Ag NWs/PDMS to an Au NT/PDMS electrode. (ii) Immobilization of HLNs on an Au NT electrode. (iii) UV-vis light-induced polymerization to form a target-imprinted MIP layer on HLNs/Au NTs. (iv) Elution of flexible MIP-ECL sensors. (v) Epidermal analyte detection. The corresponding ECL signals are displayed above the bottom three graphs, respectively.
