Construction of ratiometric fluorescence sensor and test strip with smartphone based on molecularly imprinted dual-emission quantum dots for the selective and sensitive detection of domoic acid

Organosilicon‐Based Carbon Dots and Their Versatile Applications

“…synthesis, making CD-MIPs thermosensitive and serving as a temperature control gate to control lysozyme capture and release. In addition, Wang et al [126] established a double quantum dot-based molecularly imprinted proportional fluorescence sensor for the selective analysis of trace domoic acid, which exhibited high sensitivity and excellent selectivity. Then, Arslan et al [127] developed CDs of ion-imprinted polymers for ion detection of Pd (II).…”

Bioreceptors for smartphone-based food contaminants detection

“…Furthermore, alternative sophisticated constructs have been developed to monitor the binding between the target analyte and the MIP's such as MoSe2 nanoparticles for the detection of furosemide(139), CsPbBr3-based perovskite nanomaterials for nitrofurazone detection (140). Other examples include the use of magnesium and nitrogen co-doped carbon dots embedded europium metal-organic framework for the detection of oxytetracycline (141) or silicon-coated blue luminous carbon dots for the detection of domoic acid (142) where the signal was acquired according the nature from the transducer that can be electrochemiluminescence (109,139) or fluorescence (141,142) signal. Campoferri et al (143) developed a novel transducer based on iridium oxide nanoparticle immobilized onto a screen-printed electrode (SPE) followed by thermal polymerization of polypyrole in the presence of the analyte (chlorpyrifos).…”

A dinuclear CdII cluster-based stable luminescent metal–organic framework for the consecutive and visual detection of H2PO4− and OCN−

“…Compared with traditional detection methods, such as atomic absorption spectroscopy, ion chromatography and ionselective electrodes, fluorescence sensors have the advantages of high sensitivity, clear signals and dynamic real-time monitoring and visibility with the naked eye, and are widely used in the field of fluorescence sensing. [17][18][19][20][21][22] Fluorescent receptors have important applications in a wide range of areas such as supramolecular, synthetic, bioorganic, medicinal, and biological chemistry. 18,23 Compared with most fluorescent probe materials, LMOFs can be designed by connecting different organic ligands according to requirements to easily distinguish analytes and interferents through special functional groups.…”
