“…Enhanced π-π interactions can be achieved by introducing ligands or auxiliary ligands in a planar structure, or synthesizing 2D multifunctional MOF nanosheets ( Li et al, 2019c ). As for hydrogen bonding, some functional groups can be applied, such as –OH and –NH 2 ( Zhao et al, 2019a ), quaternary ammonium groups ( Wang et al, 2017 ; Yang et al, 2017 ), N-carboxymethyl-3,5-dicarboxylpyridinium bromide (H 3 CmdcpBr) ( Sun et al, 2017 ; Yang et al, 2015 ). And the structural matching between the probe DNA and MOFs should be taken into account in future MOF design ( Sun et al, 2017 ).…”

“…However, many synthesized MOFs with moderate quenching efficiency are time-consuming in the detection. To address this issue, many π-conjugated ancillary ligands including 2,2′-bipyridine (bipy) ( Sun et al, 2017 ), 1,10-phenanthroline (phen) ( Sun et al, 2017 ) and 2-(4-pyridyl)benzimidazole (pbz) ( Sun et al, 2017 ), trans -1,2-bis(4-pyridyl)ethylene (bpe) ( Zhao et al, 2016a ) and 1,2-bis(4-pyridyl)ethane (bpea) ( Zhao et al, 2016a ), 4,4′-dipyridyl sulfide (dps) ( Yang et al, 2015 ) can be integrated into sensing platform. Moreover, the planar ligands might reduce the steric hindrance of the MOFs leading to the enhanced target-probe hybridization.…”

“…Moreover, the planar ligands might reduce the steric hindrance of the MOFs leading to the enhanced target-probe hybridization. Sun et al, (2017) introduced three π-conjugated ancillary ligands of 1,10-phenanthroline (phen), 2-(4-pyridyl)benzimidazole (pbz), and 2,2′-bipyridine (bipy) into the four water-stable zwitterionic zinc carboxylate compounds for promoting π-stacking interactions with the probe ss-DNA to improve quenching efficiency. The detection platform of HIV-1 ds-DNA had a widely linear concentration in the range of 0–60 nM and a low detection limit of 7.4 nM (S/N = 3).…”

Virus severely endangers human life and health, and the detection of viruses is essential for the prevention and treatment of associated diseases. Metal-organic framework (MOF), a novel hybrid porous material which is bridged by the metal clusters and organic linkers, has become a promising biosensor platform for virus detection due to its outstanding properties including high surface area, adjustable pore size, easy modification, etc. However, the MOF-based sensing platforms for virus detection are rarely summarized. This review systematically divided the detection platforms into nucleic acid and immunological (antigen and antibody) detection, and the underlying sensing mechanisms were interpreted. The nucleic acid sensing was discussed based on the properties of MOF (such as metal ion, functional group, geometry structure, size, porosity, stability, etc.), revealing the relationship between the sensing performance and properties of MOF. Moreover, antibodies sensing based on the fluorescence detection and antigens sensing based on molecular imprinting or electrochemical immunoassay were highlighted. Furthermore, the remaining challenges and future development of MOF for virus detection were further discussed and proposed. This review will provide valuable references for the construction of sophisticated sensing platform for the detection of viruses, especially the 2019 coronavirus.

The current spread of various viruses has negatively affected human life and health. Developing enhanced virus diagnostic techniques to mitigate future outbreaks is becoming vital. Metal‐organic frameworks (MOFs) have gained significant attention for their potential applications in virus detection because of their outstanding features, including high surface area, tunable properties, and adjustable pore size. Integrating nanomaterials with MOFs can also further enhance these properties, creating a new class of materials referred to as MOF‐based nanocomposites. This review paper provides an overview of the MOF‐based nanocomposites' status and future prospects for enhanced virus detection. The recent advances in the synthesis and functionalization of MOF and MOF‐based nanocomposites for virus detection are discussed. The paper describes the different types of detection platforms, including nucleic acid and immunological detection, as well as the mechanisms of MOF‐based sensors and the techniques used to synthesize MOFs and MOF‐based nanocomposites for virus detection. Additionally, the review paper explores the potential of integrating MOFs into real sensing devices and their prospects in real‐life applications. Finally, the paper examines the current challenges of these biosensing platforms. Overall, the review paper highlights the capability of MOFs and MOF‐based nanocomposites as versatile and practical platforms for virus detection and provides a comprehensive overview of the latest advancements in this area of research.
