The respective molecular structure of MC-RR and its arginine positions (a). The mechanism of the dummy fragment imprinting and rebinding MC-RR target (b). The synthetic method (c) and mechanism (d) of MIPs-wrapped ZnFe2O4 NPs. The manufacture of ZnFe2O4@MIPs modified paper-based fluorescence sensing site and corresponding sensing mechanism (e). Anchoring ZnFe2O4@MIPs on paper-based fluorescence substrate by soaking and shaker (f). g It displays various region functions of the μSPAD and assembly processes for the device. h, i Figure showed schematic diagram of operation process of sample injection (h) and fluorescence analysis (i) on the μSPAD.
