“…Metal‐organic frameworks (MOFs) are a kind of new multifunctional porous materials. Due to their unique and novel properties such as big surface areas, controllable morphology and pore sizes, varied structures and unsaturated coordination sites, these materials have widely employed for gas adsorption and separation , catalysis , drug release and so on . By comparison, their electrochemical sensing applications are still in their infancy stage .…”

A nanocomposite of HKUST‐1 (MOF) and electroreduction graphene oxide (ERGO) is prepared and applied as an electrochemical sensor for the simultaneous determination of paracetamol and dopamine by means of one‐step electrodeposition. The MOF/ERGO composite displays excellent electrochemical catalytic activities towards the paracetamol and dopamine, which is attributed to the synergistic effect of big surface area, porosity and high electrocataytic activity of the MOF and good conductivity of ERGO. The modified electrode could be applied to determine simultaneously paracetamol and dopamine in biochemical samples with wide linear ranges (0.2 μM to 160 μM for paracetamol and 0.2 μM to 300 μM for dopamine) and low detection limits (0.016 μM for paracetamol and 0.013 μM for dopamine). Meanwhile, the proposed sensor still displays high sensitivity, good selectivity and excellent stability.

“…It is important to highlight the sensitivity of the MOF-based sensors linked to the electroanalytical applications. Thus, detection limits range from 0.8 nM for Ponceau 4R in soft drinks (only requiring 43 mg of MOF) [117] to 1.45 µM for hydrazine in waters (in this case requiring 100 mg of MOF) [121]. Furthermore, electroanalytical methods are quite efficient, fast and simple, thus in accordance with GAC.…”

“…For instance, some MOFs have semiconductor-like properties, and can serve as photoelectric materials [116]. These properties depend in some cases on the metal nature of the MOF, in other cases on the properties imparted by the organic ligands, and in others on the resulting crystal [117]. When incorporated to certain analytical spectroscopic applications, particularly luminescence-based, the MOF design is also important to ensure proper characteristics in the resulting material.…”

“…MOFs incorporate synthetically in the working electrode by proper modification of the support material, with the purpose of attaining ultra-functional sensors. Thus, Asadi et al [121] and Ji et al [117] described carbon paste electrodes (CPE) modified with neat MOFs, such as ZIF-67 and Ni-BTC. MOFs can be combined with nanoparticles with the purpose of improving the overall electrochemical behavior of the resulting composite [121].…”

Metal-organic frameworks (MOFs) are porous hybrid materials composed of metal ions and organic linkers, characterized by their crystallinity and by the highest known surface areas. MOFs structures present accessible cages, tunnels and modifiable pores, together with adequate mechanical and thermal stability. Their outstanding properties have led to their recognition as revolutionary materials in recent years. Analytical chemistry has also benefited from the potential of MOF applications. MOFs succeed as sorbent materials in extraction and microextraction procedures, as sensors, and as stationary or pseudo-stationary phases in chromatographic systems. To date, around 100 different MOFs form part of those analytical applications. This review intends to give an overview on the use of MOFs in analytical chemistry in recent years (2017–2019) within the framework of green analytical chemistry requirements, with a particular emphasis on possible toxicity issues of neat MOFs and trends to ensure green approaches in their preparation.

“…Studies revealed that three MOFs have some of the properties similar to each other. Investigation on ponceau-4R gave the detection limit of 80 pM in 0.5-150 nM concentration range [193]. The gravimetric-type gas sensing application of Ni-MOF-74 was explored with resonant cantilever sensors in the ultrasensitive examination of carbon monoxide.…”
