“…For example, Zhang's group employed single-emission copper-doped ZnS QDs (ZnS: Cu QDs) to detect TC in milk. 257 Upon the addition of TC, the original fluorescence of the ZnS: Cu QDs at 578 nm was quenched, while a new green fluorescence emission at 520 nm stemming from TCs-Zn(bix) ternary complexes appeared. Using this new green emission, TC could be distinguished from other types of antibiotics.…”

“…Tetracycline (TC), as a broad-spectrum antibiotic, has been widely utilized as the drugs of infectious diseases. , Therefore, it is of paramount importance to develop a convenient, rapid, low-cost, highly sensitive and selective sensor for on-site analysis of TC is highly desirable. , Currently, various traditional analytical techniques have been used for TC analysis, mainly including high performance liquid chromatography (HPLC), , capillary electrophoresis (CE), electrochemical and colorimetric . These methods are difficult to achieve on-site monitoring of TCs due to their high cost, sophisticated instruments, time-consuming, complicated sample preparation, poorly reproducible, and skilled personnel.…”

Dual-state emitters (DSEs) are entities that exhibit fluorescence in both the solution and solid state, which open up a wide range of possibilities for their utilization in various fields. The development of detection platforms using intrinsic luminescent metal–organic frameworks (LMOFs) is highly desirable for a variety of applications. DSE MOFs as a subclass of intrinsic LMOFs are highly attractive due to no need for encapsulation/functionalization by fluorophores and/or using luminescent linkers. Herein, a highly stable intrinsic dual-state blue emission (λem = 425 nm) zinc-based MOF with rodlike nanostructures (denoted as UoZ-2) was synthesized and characterized. To the best of our knowledge, intrinsic DSE of Zn-MOFs with blue emission in the dispersed form in solution and solid-state fluorescence have not been reported yet. When tetracycline (TC) was added, a continuous color evolution from blue to greenish-yellow with dramatic enhancement was observed due to aggregation induced emission (AIE). Thus, a sensitive ratiometry-based visual detection platform, in solution and on paper independently, was designed for detection of TC exploiting the DSE and AIE properties of UoZ-2 alone and UoZ-2:TC. The detection limit was estimated to be 4.5 nM, which is considered to be one of the most sensitive ratiometric fluorescent probes for TC sensing. The ratiometry paper-based UoZ-2 sensor displays a reliable TC quantitative analysis by recognizing RGB values in the on-site TC detection with satisfactory recoveries.

“…However, the above techniques require long analysis time and expensive instruments, which make it difficult to achieve real-time analysis of large-scale samples. In addition, electrochemical, 5 fluorescent 6 and chemiluminescent (CL) 7 sensors have been developed for the detection of TCs due to their advantages of low detection limit and fast detection speed, but they still require complex electrode processing procedures or rely on toxic organic compounds as fluorescent sources. Colorimetry, by contrast, is one of the simplest detection methods that depends on the variation of color during the detection program.…”
