“…For example, Lu et al reported a bimetallic MOFs-based fluorescent aptasensor for the detection of chloramphenicol [ 167 ]. Amalraj et al developed a dual-mode MOFs-based fluorescent aptasensor for simultaneous determination of 17β-estradiol and chloramphenicol using two different dyes-labeled aptamers [ 168 ]. Ochratoxin A (OTA) is primarily generated through the consumption of improperly stored food products and uptake of OTA may cause organ damage.…”

Taking advantage of high porosity, large surface area, tunable nanostructures and ease of functionalization, metal-organic frameworks (MOFs) have been popularly applied in different fields, including adsorption and separation, heterogeneous catalysis, drug delivery, light harvesting, and chemical/biological sensing. The abundant active sites for specific recognition and adjustable optical and electrical characteristics allow for the design of various sensing platforms with MOFs as promising candidates. In this review, we systematically introduce the recent advancements of MOFs-based fluorescent chemosensors and biosensors, mainly focusing on the sensing mechanisms and analytes, including inorganic ions, small organic molecules and biomarkers (e.g., small biomolecules, nucleic acids, proteins, enzymes, and tumor cells). This review may provide valuable references for the development of novel MOFs-based sensing platforms to meet the requirements of environment monitoring and clinical diagnosis.

“…Residual environmental hormones are becoming a public concern because of their severe risks to human health. Amalraj et al designed a fluorescent biosensor for the simultaneous detection of CAP and 17β-estradiol based on a MOF-MoS 2 nanomaterial and an enzyme-assisted signal amplification strategy [ 129 ]. The MOF coupled with MoS 2 sheets (MOF-MoS 2 ) was used as an efficient fluorescent nanoquencher.…”

Food safety issues have become a major threat to public health and have garnered considerable attention. Rapid and effective detection methods are crucial for ensuring food safety. Recently, nanostructured fluorescent materials have shown considerable potential for monitoring the quality and safety of food because of their fascinating optical characteristics at the nanoscale. In this review, we first introduce biomaterials and nanomaterials for food safety analysis. Subsequently, we perform a comprehensive analysis of food safety using fluorescent biosensors based on nanomaterials, including mycotoxins, heavy metals, antibiotics, pesticide residues, foodborne pathogens, and illegal additives. Finally, we provide new insights and discuss future approaches for the development of food safety detection, with the aim of improving fluorescence detection methods for the practical application of nanomaterials to ensure food safety and protect human health.

“…Multicolour fluorescence detection is the most efficient method for detecting multiple biomolecules. [14][15][16] FRET is a method wherein energy is transferred between fluorescence elements (various fluorophores, carbon quantum dots, and up conversion nanoparticles, for example) as donors and quenching materials (metal oxides, graphene oxide, MoS 2 and various MOFs, [17][18][19] for example) as acceptors. Whenever the distance between the donor and acceptor is less than 10 nm, the fluorescence could be quenched due to the overlapping of the energy donor's emission spectrum and the energy acceptor's absorption spectrum.…”
