Intrinsic Dual-State Emission Zinc-Based MOF Rodlike Nanostructures with Applications in Smartphone Readout Visual-Based Detection for Tetracycline: MOF-Based Color Tonality

“…Metal–organic frameworks (MOFs) are porous crystalline materials prepared by metal ions/clusters and organic ligands linking by coordination bonds. − MOFs have been intensively investigated for biochemical applications due to their distinctive physicochemical features including high thermal stability, high surface area, porosity, presence of cavities and functionality. − Many optical-based applications require stable, durable, and effective luminescent materials. , Luminescent metal–organic frameworks (LMOFs), as a part of the metal–organic frameworks (MOFs) family, are gaining great attention recently due to their enormous applications in bio­(chemical) sensing and bioimaging. − Although many functionalizations of MOFs have been reported to prepare LMOFs, such as using fluorescent linker in MOF and/or insertion of luminophores into the MOF structure such as nanoclusters, carbon dot, and fluorescent dyes, the fabrication of MOFs with intrinsic luminescence is more practical and valuable for many applications due to stability of the MOFs and low-cost precursors . In the literature, for the construction of intrinsic LMOFs, lanthanide elements, such as Eu 3+ and Tb 3+ are used. ,,, Such elements have higher costs, potential supply shortages, and adverse effects on the environment.…”

Synthesis of MnO2 sub-microspheres with effective oxidase-mimicking nanozymes for the colorimetric assay of ascorbic acid in orange fruits and juice

“…1 To monitor AA levels, the rapid, simple, low-cost, and accurate detection of AA in food and its products is required. There are numerous methods for detecting AA, such as fluorescence spectrophotometry, 2,3 electrochemistry, 4 high-performance liquid chromatography, 5 and chemiluminescence. 6 Although these methods and techniques yield reliable results, they suffer from some limitations, including complicated instrumentation, expensive instruments, and the requirement of skilled personnel.…”

Accuracy improvement via novel ratiometry design in distance-based microfluidic paper based analytical device: instrument-free point of care testing

“…Currently, numerous analytical techniques developed for the determination of various biological molecules, such as electrochemistry, 5,6 high-performance liquid chromatography, 7 uorescence, [8][9][10][11][12] colorimetry, [13][14][15][16][17] chemiluminescence, 18 capillary electrophoresis, 19 and the enzyme-linked immunosorbent assay (ELISA). 20,21 However, most of these methods and techniques suffer from obstacles such as the need for costly and sophisticated instruments, skilled personnel, complicated pretreatments, or costly biological reagents.…”
