“…[Cu(mal)(bpy)]•2H 2 O (Cu MOFs) was prepared with a little modification according to the reported method. 36 Cu(OAc) 2 (0.0816 g, 0.15 mmol), D,L-malic acid (0.1260 g, 0.3 mmol), and 4,4′-bipyridyl (0.0702 g, 0.15 mmol) in 9 mL of water/methanol mixture (1:1, v/v) were sealed in a glass tube. The mixture was heated at 100 °C for 24 h. Big dark blue square crystals were harvested and washed with methanol, and then vacuumdried at 70 °C for 3 h.…”

Most of the reported metal organic frameworks (MOFs)-based DNA sensors were developed by utilizing the different adsorption capacities of MOFs to different structural DNAs (for example, single-stranded DNAs (ssDNAs) and double-stranded DNAs (dsDNAs)) or ssDNAs with different lengths. Herein, we introduced another strategy for the design of MOFs-based biosensing platforms. We found that specific small-sized amino acids (for example, glycine and serine) could lead to the destruction of the MOFs formed by [Cu(mal)(bpy)]·2HO], thus recovering the fluorescence of a fluorophore-labeled ssDNA that had been quenched by MOFs. The corresponding working mechanism was discussed. On the basis of this finding, a mix-and-detect fluorescence method was designed for the turn-on detection of specific small-sized amino acids. The feasibility of its use in real serum samples was also demonstrated. Besides biosensing applications, the discovery of amino acids-triggered destruction of MOFs can also enrich the building blocks of molecular logic gate. As an example, a biomolecular logic gate that performs OR logic operation was constructed using glycine and a DNA strand as inputs.

In this work, a [Cu(mal)(bpy)]⋅H2O (mal, L-(-)-malic acid; bpy, 4,4'-bipyridyl) homochiral metal-organic frameworks (MOFs) was synthesized and used for modifying the inner walls of capillary columns by utilizing amido bonds to form covalent links between the MOFs particles and capillary inner wall. The synthesized [Cu(mal)(bpy)]⋅H2 O and MOFs-modified capillary column were characterized by X-ray diffraction, thermogravimetric analysis, particle size distribution analysis, nitrogen absorption characterization, FTIR spectroscopy, SEM, and energy-dispersive X-ray spectroscopy (EDX). The MOFs-modified capillary column was used for the stereoisomer separation of some drugs. The LODs and LOQs of six analytes were 0.1 and 0.25 μg/mL, respectively. The linear range was 0.25-250 μg/mL for ephedrine, 0.25-250 μg/mL for pseudoephedrine, 0.25-180 μg/mL for D-penicillamine, 0.25-120 μg/mL for L-penicillamine, 0.25-180 μg/mL for D-phenylalanine, and 0.25-160 μg/mL for L-phenylalanine, all with R(2) > 0.999. Finally, the MOFs-modified capillary column was applied for the analysis of active ingredients in a real sample of the traditional Chinese medicine ephedra.

“…L-malic acid has been used to synthesise homochiral MOFs, involving metals such as Mn, Ni, Cu, Co and Ca [126][127][128][129][130]. In 2013 and 2014, Fedin et al reported multiple Cu and Ni based homochiral MOFs using L-malate and N donor ligands, such as bpy (4,4 -bipyridyl) and bpe (trans-1,2-bis(4-pyridyl)ethylene) ( Figure 13) [129,130]. The Cu(II)-malate layers and Ni(II)-malate chains were connected by the N-donor linkers, different lengths of which could be used to control the size of pores.…”

Metal-organic frameworks (MOFs) have found uses in adsorption, catalysis, gas storage and other industrial applications. Metal Biomolecule Frameworks (bioMOFs) represent an overlap between inorganic, material and medicinal sciences, utilising the porous frameworks for biologically relevant purposes. This review details advances in bioMOFs, looking at the synthesis, properties and applications of both bioinspired materials and MOFs used for bioapplications, such as drug delivery, imaging and catalysis, with a focus on examples from the last five years.
