Hierarchically porous RhB-encapsulated ZIF-7 as a dual-emission fluorescence probe for ultrasensitive detection of melamine in infant formulations.

ABSTRACT: Melamine is an unauthorized food additive and a highly concerning adulterant in foods that can occur either accidently or intentionally in dairy products, with potential health risks upon exposure to higher concentrations. An ultrasensitive fluorescent probe based on dual emissive RhB _x @ZIF-7 was developed to detect melamine. In this study, a fluorescent dye, Rhodamine B (RhB), was successfully encapsulated into the metal-organic framework (MOF) pores of ZIF-7 to form a fluorescent probe (RhB₃₀@ZIF-7), with dual emission properties to enable the detection of melamine at low concentrations. RhB₃₀@ZIF-7 was optimized by varying experimental parameters, including temperature (25 °C), pH (7.0), incubation time (10 min), and probe concentration (1 mg mL<
