Three novel metal–organic frameworks with different coordination modes for trace detection of anthrax biomarkers

Abstract

Dipicolinate acid (DPA) is an anthrax biomarker. It's serious consequences make it's detection in great need. In this paper, three novel metal-organic frameworks (MOFs) with different coordination modes were synthesized...

Recent progress of metal–organic frameworks as sensors in (bio)analytical fields: towards real-world applications

“…MOFs sensing materials have emerged for biomedical applications principally due to their low cytotoxicity (which is critical for eventual in vivo applications), intrinsic biodegradability, biological affinity, and the possibility of integrating biomolecules in the MOF structures (i.e., to prepare biosensors). Recently developed MOF sensing materials have been used for the detection of (i) pharmaceutical drugs [ 65 ]; (ii) biomarkers for non-communicable diseases, such as cardiac troponin (myocardial injuries) [ 66 ], microRNA (different disease states) [ 67 ], or VOCs (in the breath of patients and related to different diseases) [ 68 ]; (iii) specific biomarkers for communicable diseases (e.g., tuberculosis, malaria, hepatitis, HIV/AIDS), such as MPT64 and ESAT-6 proteins (biomarkers secreted by Mycobacterium tuberculosis ) [ 69 , 70 ], or dipicolinic acid (biomarker for anthrax) [ 71 ]; (iv) pathogens (virus, bacterium, or fungus), such as Pseudomonas Aeruginosa [ 72 ], hepatitis-C [ 73 ], human immunodeficiency virus type 1 (HIV-1) [ 74 ], and Ebola [ 75 ].…”

Highly selective C2H2and CO2capture based on two new ZnII-MOFs and fluorescence sensing of two doped MOFs with EuIII

“…[1][2][3][4] Compared with traditional porous materials such as charcoal and zeolite, MOFs have many interesting characteristics, such as variable topological characteristics, adjustable function, gas adsorption and storage, gas separation ability and excellent optical properties. [5][6][7][8][9][10][11][12][13][14][15][16] As we all know, the structure of MOFs mainly depends on the selection and design of ligands. Pyridine in ligands can change the flexibility of the skeleton, 17,18 and the coordinated N atom in the structure can affect the gas adsorption of MOFs.…”

High Emission Zinc Metal‐Organic Framework for Sensitive and Selective Detection of Fe3+, Cr6+ and Nitrofurazone Antibiotic

“…[15] Fluorescence detection based on MOFs has gradually attracted widespread attention because of its advantages of simple processing, high sensitivity and selectivity, fast response and visibility. [16][17][18] In previous work, we have reported a fluorescent Zn-MOF material based on ligand 2-bpmh (2-bpmh = N, N'-bis-pyridin-2-ylmethylene-hydrazine) and H 2 BDC (H 2 BDC = phthalic acid). Due to the participation of tertiary N atoms in the coordination, structural stability of the Zn-MOF is greatly improved.…”

“…Metal‐organic frameworks (MOFs) are highly adjustable and obtain pre‐designed structures through rational selection of organic ligands and metal nodes, so they are favored by scientists in various fields [15] . Fluorescence detection based on MOFs has gradually attracted widespread attention because of its advantages of simple processing, high sensitivity and selectivity, fast response and visibility [16–18] . In previous work, we have reported a fluorescent Zn‐MOF material based on ligand 2‐bpmh (2‐bpmh=N, N’‐bis‐pyridin‐2‐ylmethylene‐hydrazine) and H 2 BDC (H 2 BDC=phthalic acid).…”
