“…The applicability of the new method for the CAP determination in shrimp samples was evaluated by a comparison with a commercial ELISA kit with the sample pretreatment proposed by the ELISA kit. The recoveries were found (91.25-104.47%) in spiked shrimp tissues and the relative standard deviation values RSD that were found 2.83%-5.02% suggested the fine accuracy and the good precision of the proposed assay [46].…”

“…In fish, pork and milk samples recoveries ranged between 96.35% and 102.57%, while the LODs were found between 0.28 nM-0.30 nM [45]. The same research group developed a ratiometric fluorescent sensing method for the determination of trace chloramphenicol (CAP) levels in shrimp tissues [46]. They developed a highly stable zirconium-porphyrin MOF (PCN-222) fluorescence quencher with strongly adsorbed dye-labeled Fam-aptamer due to π-π stacking, hydrogen bond and coordination interactions ( Figure 4).…”

The determination of organic and inorganic pollutants in fish samples is a complex and demanding process, due to their high protein and fat content. Various novel sorbents including graphene, graphene oxide, molecular imprinted polymers, carbon nanotubes and metal-organic frameworks (MOFs) have been reported for the extraction and preconcentration of a wide range of contaminants from fish tissue. MOFs are crystalline porous materials that are composed of metal ions or clusters coordinated with organic linkers. Those materials exhibit extraordinary properties including high surface area, tunable pore size as well as good thermal and chemical stability. Therefore, metal-organic frameworks have been recently used in many fields of analytical chemistry including sample pretreatment, fabrication of stationary phases and chiral separations. Various MOFs, and especially their composites or hybrids, have been successfully utilized for the sample preparation of fish samples for the determination of organic (i.e., antibiotics, antimicrobial compounds, polycyclic aromatic hydrocarbons, etc.) and inorganic pollutants (i.e., mercury, palladium, cadmium, lead, etc.) as such or after functionalization with organic compounds.

“…These advantages also make MOFs popular in sample preparation of aquatic products to improve the efficiency of the extraction and enrichment and achieve better recover-ies [29,71,72]. Currently, MOFs have been used in sample preparation for selective separation and analysis of different compounds from aquatic products such as neurotoxin [73], heavy metals [74], antibiotics drugs [75][76][77][78], polycyclic aromatic hydrocarbons (PAHs) [79]. The size-selective adsorption process of guest molecules on MOF is mainly performed in the cavities, and the specific adsorption is attributed to the interaction between active sites and analytes including π-π interactions, Hbonding, and hydrophobic-hydrophilic interactions, etc [70][71][72].…”

Safety analysis of aquatic products has been a challenge in recent years due to the serious matrix interference, complex characteristics, and ultra-low content of analytes. Introducing advanced materials to sample preparation technique can greatly improve the extraction, enrichment, and separation for further qualification and quantification of target analytes by coupling with consequent analytical technologies. Based on this scope, this review is mainly introducing advanced materials on the sample preparation for safety analysis of aquatic products in the past decade. After introducing the importance of the corresponding advanced materials, advanced materials are used for the sample preparation and in the improvement of safety analysis result of aquatic products. Advanced materials for sample preparation of aquatic products were reviewed including carbon materials, metal organic frameworks, covalent organic frameworks, molecularly/ions imprinted polymers, etc. Then, applications of the advanced materials for the analysis of specific fishery analytes (antibiotics, anesthetic, preservatives, etc.) were briefly introduced. Conclusions and perspectives on advanced materials for sample preparation and safety analysis of aquatic products were also presented.

Thin‐film fluorescent sensors play critical roles in the gas sensing field. However, fluorescent sensing materials for practical applications are limited, because of the aggregation‐caused quenching (ACQ) effect and photobleaching. This study investigates a host–guest thin‐film fluorescence sensor by incorporating a fluorescent probe into a metal–organic framework (MOF). The fluorescent molecule Me4BOPHY‐1 acts as a recognition probe for the neurotoxin analog diethylchlorophosphite (DCP). The MOF (ZIF‐8) provides nanocavities for the confinement of guest molecules, which reduces the self‐aggregation of fluorescent molecules and pre‐enriches the target gas. By applying ZIF‐8 framework to disperse the fluorescent molecules, the ACQ effect of Me4BOPHY‐1 can be effectively overcome. The fluorescence quantum efficiency of the molecules is increased from 0.76% to 19.72%, which enables its ability for gas sensing with a fast response time of 3 s and a detection limit as low as 1.13 ppb. Besides, the MOF facilitates selectivity enhancement through the confinement effect, weakening the sensing response to the interference of HCl. Moreover, the confinement effect also ensures high photo‐stability as well as thermal stability. It can maintain fluorescence intensity under 4800 s’ laser irradiation. Thus, the host–guest design strategy offers a thin‐film fluorescence gas sensor with high 3S (sensitivity, selectivity, and stability) toward neurotoxin analytes.
