Abstract
ConspectusMany living organisms are capable of producing inorganic materials of precisely controlled structure and morphology. This ubiquitous process is termed biomineralization and is observed in nature from the macroscale (e.g., formation of exoskeletons) down to the nanoscale (e.g., mineral storage and transportation in proteins). Extensive research efforts have pursued replicating this chemistry with the overarching aims of synthesizing new materials of unprecedented physical properties and understanding the complex mechanisms that occur at the biological–inorganic interface.Recently, we demonstrated that a class of porous materials termed metal–organic frameworks (MOFs) can spontaneously form on protein-based hydrogels via a process analogous to natural matrix-mediated biomineralization. Subsequently, this strategy was extended to functional biomacromolecules, including proteins and DNA, which have been shown to seed and accelerate crystallization of MOFs. Alternative strategies exploit co-precipita...

Abstract In this work, a novel hydrogen peroxide (H 2 O 2 ) biosensor was developed based on the microperoxidase-11 (MP-11) encapsulated in metal-organic frameworks, PCN-333 (Al) (PCN stands for porous coordination network), which was grown on the three-dimensional (3D) kenaf stem-derived porous carbon (3D-KSC) firmly and uniformly. The ball-flower-like PCN-333 (Al) with mesopores of 5.5 nm was especially suitable for encapsulating MP-11 (1.1 × 1.7 × 3.3 nm). Scanning electron microscopy and ene...

: Zeolitic imidazolate framework-8 (ZIF-8) grown around antibodies anchored to plasmonic nanostructures serves as a protective layer to preserve the biorecognition ability of antibodies stored at room and elevated temperatures for several days. The biofunctionality of the ZIF-8-protected biochip can be restored by a simple water-rinsing step, making it highly convenient for use in point-of-care and resource-limited settings.

One of the most attractive characteristics of metal organic frameworks (MOFs) is their diversity in use as functional materials, because their diversity means that the appropriate MOFs for the required applications can be readily generated from numerous elemental compounds. In addition, post-synthetic modifications of MOFs further expand their diversity. We describe a combined approach involving a typical post-synthetic modification and our previously reported surface modification to introduce m...

The use of metal–organic frameworks (MOFs) as immobilization matrices for enzymes as a platform for emerging applications is reported. In addition to an overview of strategies developed to prepare enzyme–MOF biocomposites, the features that render MOFs interesting matrices for bio-immobilization are highlighted along with their potential benefits beyond a solid-state support in the design of innovative biocomposites.

A hierarchical porous metal–organic framework (MOF), PCN-888, containing three types of cavities was utilized to couple two enzymes into a tandem nanoreactor. The largest cavity (6.2 nm) can only accommodate one molecule of glucose oxidase (GOx). The intermediate cavity (5.0 nm) can accommodate one and only one molecule of horseradish peroxidase (HRP). The small cavity (2.0 nm) has sufficient size for neither GOx nor HRP, and remains open as a substrate diffusion pathway. The coupling of the two...

We report the synthesis and characterization of a water-stable zirconium metal–organic framework (MOF), NU-1003, featuring the largest mesoporous aperture known for a zirconium MOF. This material has been used to immobilize the nerve agent hydrolyzing enzyme, organophosphorus acid anhydrolase (OPAA). The catalytic efficiency of immobilized OPAA in nanosized NU-1003 is significantly increased compared to that of OPAA immobilized in microsized NU-1003 and even exceeds that of the free OPAA enzyme....

Abstract We report a molecular simulation study to investigate a helical peptide (β-adrenoceptor) confined in two metal-organic frameworks (MOFs) namely IRMOF-74-II and -III. Reversible structural transformation between the major (α-helix and 310-helix) and minor structures (bend, turn and coil) of the confined peptide is observed. In IRMOF-74-II, the peptide is over-confined and the helicity is lower compared to that in bulk water; however, the helicity is enhanced upon moderately confined in I...

Enhancing the activity and stability of enzymes and improving their reusability are critical challenges in the field of enzyme immobilization. Here we report a facile and efficient biomimetic mineralization to embed thermophilic lipase QLM in zeolite imidazolate framework-8 (ZIF-8). Systematic characterization indicated that the entrapment of lipase molecules was successfully achieved during the crystal growth of ZIF-8 with an enzyme loading of ∼72.2 ± 1.88 mg/g lipase@ZIF-8, and the enzymes cou...

Nanoparticulate delivery platforms have shown promising advantages for vaccines in many aspects. However, their application was limited so far by lengthy synthetic protocols, the requirement of specific modification of antigen, and by the low efficiency in inducing antigen-specific cytotoxic T-lymphocyte responses. This study demonstrates for the first time the construction of metal-organic-framework (MOF) based vaccines by encapsulating ovalbumin (OVA) and attaching the cytosine-phosphate-guani...

Abstract null null In this work, a novel electrochemical aptasensor based on Fe-based MOFs was fabricated. To enhance sensitivity to the detection of antibiotics, NH2-MIL-101(Fe)/CNF@AuNPs was synthesized by a combination of hydrothermal, electrospinning, pyrolysis and electrodeposition methods. Subsequently aptamer could be attached to the NH2-MIL-101(Fe)/CNF@AuNPs through “Au-S” bonds. The electrical signals generated from the interaction between antibiotics and aptamers were amplified by the ...

Abstract null null Recycle CO2 as a chemical feedstock and as renewable energy generated sustainable solution benefiting both environment and economy. However, advancements in highly efficient CO2 conversion at ambient condition are still hampered, mainly due to the inherent thermodynamic stability of CO2 which lead to the low conversion efficiency and required harsh catalyzing conditions (high temperature, high pressure, and toxic solvents, etc.). In this study, two unique gridlike 3d-4f hetero...

Abstract null null Recently, Zirconium (Zr) based metal organic frameworks (Zr-MOFs) materials have gathered increasing interest in the field of photocatalysis. Zr-MOFs not only have the large surface area, orderly porous structure, and tunable organic bridging linker/metal clusters as other MOFs, but also possess higher thermal stability and excellent water-tolerant than most of other MOFs. In this review, the Zr-MOFs with excellent photocatalytic properties reported in recent years are reviewe...
