Published: May 14, 2024

The construction of a highly luminescent, stable, and target-insensitive internal reference signal is significant in ratiometric color tonality applications. Improvement the antenna effect, efficient mechanism that enhances luminescence emission via sensitization, an effective route to obtain bright luminescence. Additionally, manipulation crystal structure morphology key issue control reactivity, especially metal–organic frameworks (MOFs). In present work, novel red emitter Eu/Zn bimetal biligand MOF (UoZ-5) was synthesized used as signal. A dual-antenna from triplet states (T1) ligands 5Do Eu3+ ion, observed explained on basis energy levels. With UoZ-5 serving reference, blue-emitting carbon quantum dots (CQDs) selective for Ag+ ions nonfluorescent composite, CQDs@Ag+, probe vitamin B1, tonality-based platform analysis were developed.

Mycotoxins are responsible for several diseases in human and animals which impose huge medical economical burdens worldwide, especially low-income countries. Therefore, many countries set regulations maximum permissible amounts of mycotoxins food that need detection methods to monitor the mycotoxin concentration. Conventional like Enzyme‐linked immunosorbent assay (ELISA), high-performance liquid chromatography (HPLC) with fluorescence (HPLC-FLD), chromatography-tandem mass spectrometry (LC-MS/MS) gas (GC) widely used quantitatively mycotoxins. However, these have limitations make them suitable laboratories factories, but cannot be regularly daily markets. Thus, pursuit sensitive, specific, handheld, low-cost as effective elective strategies point-of-care testing (POCT) has gotten much consideration recent years. POCT is one ultimate objectives determination, so test must quick, particular, delicate, open, simple used. In this review, after a brief introduction their importance, common tools advantages disadvantages discussed, then lateral flow (LFA) systems working principles, classifications, method explained. Furthermore, some studies regarding development LFA detecting types innovations LFAs' design techniques overcoming traditional comprehensively reviewed. Various utilized extend sensitivity give quantitative sensing. Utilizing numerous visualization strategies, utilizing distinctive labeled reporters, coordination other take advantage both gadgets, utilize restrictive membranes upgrade reagent reactivity, few examined literature update use determination mycotoxins, covers.
