“…To detect the glucose level in human serum condition, the Wang group successfully synthesized a UiO‐67@Ni‐MOF core–shell architecture, containing a nonenzyme‐based sensor, which has stability and cost advantages compared to enzyme‐based sensors (Figure 10). 41 UiO‐67 was selected as the core because of its large surface area and good conductivity, resulting in an enhanced rate of electron transfer within the core–shell architecture. The Ni‐MOF shell acted as an electrocatalytic material, due to its high electrochemical performance in glucose oxidation.…”

Metal-organic frameworks (MOFs) are porous crystalline materials with a high tunability. To improve the functionality of the original frameworks, several strategies, such as the use of different metal cations and organic ligands and post-synthetic modification, have been developed, enabling the use of MOFs in numerous practical applications in various fields. Recently, another approach, i.e., MOF-on-MOF architecturing, has been actively studied by combining two or more MOFs into a composite. MOF-on-MOF materials not only possess the intrinsic properties of each MOF but also exhibit unprecedented synergism within a single system, resulting in a considerable potential for various applications. This review summarizes the interesting areas of application of MOF-on-MOF architectures into three categories: separation, catalysis, and sensing. In particular, the synergism occurring within such MOF-on-MOF architectures is discussed.

Metal-organic frameworks (MOFs) offer a unique variety of properties and morphology of the structure that make it possible to extend the performance of existing and design new electrochemical biosensors. High porosity, variable size and morphology, compatibility with common components of electrochemical sensors, and easy combination with bioreceptors make MOFs very attractive for application in the assembly of electrochemical aptasensors. In this review, the progress in the synthesis and application of the MOFs in electrochemical aptasensors are considered with an emphasis on the role of the MOF materials in aptamer immobilization and signal generation. The literature information of the use of MOFs in electrochemical aptasensors is classified in accordance with the nature and role of MOFs and a signal mode. In conclusion, future trends in the application of MOFs in electrochemical aptasensors are briefly discussed.

“…A definite advantage of metal organic complexes in comparison with other forms is possibility of fine tune of electronic structure on molecular level due to variation of ligands: the stronger the pull‐off of the electron density from the metal ion, the lower the overvoltage of the electrochemical reaction will take place. Several types of nickel‐contained complexes, namely half‐sandwich nickel(II) complexes of coumarin substituted N‐heterocyclic carbenes [23], nickel thiolates [24], core‐shell UiO‐67@Ni‐MOF composites [25], nano nickel‐coordination polymers [26], were synthesized and used as electrocatalysts in electrochemical glucose detecting with high sensitivity. Unfortunately, despite allegations of high selectivity, its mechanisms were not explained and justified.…”

In this paper a new enzymeless electrochemical glucose sensor based on carboxylated multiwalled carbon nanotubes (cMWCNT) with immobilized nickel (II) acetylacetonate (NiL) as electrocatalyst and molecularly imprinted polymer fabricated through electrostatic self‐assembling of polyethyleneimine (PEI) crosslinked with glutaric dialdehyde (GDA). The electrocatalytic properties of NiL and PEI‐cMWCNT, PEI‐GDA and PEI‐glucose interactions is studied for the first time. Developed sensor demonstrates excellent electrocatalytic activity towards glucose oxidation and possessing high stability, sensitivity of 5897.42±161.00 μA ⋅ mM−1 cm−2, LOD of 0.138 mM and high selectivity in the presence of creatinine, L‐alanine, glycine, D‐glutamine, uric acid, L‐ascorbic acid, urea and BSA.
