Metal–Organic Framework-Based Enzyme Biocomposites

Chemical Reviews, Journal Year: 2021, Volume and Issue: 121(3), P. 1077 - 1129

Published: Jan. 13, 2021

Because of their efficiency, selectivity, and environmental sustainability, there are significant opportunities for enzymes in chemical synthesis biotechnology. However, as the three-dimensional active structure is predominantly maintained by weaker noncovalent interactions, thermal, pH, stressors can modify or eliminate activity. Metal–organic frameworks (MOFs), which extended porous network materials assembled a bottom-up building block approach from metal-based nodes organic linkers, be used to afford protection enzymes. The self-assembled structures MOFs encase an enzyme process called encapsulation when MOF synthesized presence biomolecule. Alternatively, infiltrated into mesoporous surface bound via covalent processes. Integration this way affords allows maintain activity challenge conditions (e.g., denaturing agents, elevated temperature, non-native solvents). In addition forming simple enzyme/MOF biocomposites, other introduced composites improve recovery facilitate advanced applications sensing fuel cell technology. This review canvasses encapsulation, pore infiltration, adsorption summarizes strategies form multicomponent composites. Also, given that biocomposites straddle chemistry enzymology, provides assessment characterization methodologies MOF-immobilized identifies some key parameters development field.

Chemical Reviews, Journal Year: 2019, Volume and Issue: 119(16), P. 9509 - 9558

Published: June 25, 2019

The ever-increasing demands for clean and sustainable energy sources combined with rapid advances in biointegrated portable or implantable electronic devices have stimulated intensive research activities enzymatic (bio)fuel cells (EFCs). use of renewable biocatalysts, the utilization abundant green, safe, high density fuels, together capability working at modest biocompatible conditions make EFCs promising as next generation alternative power sources. However, main challenges (low density, relatively low poor operational stability, limited voltage output) hinder future applications EFCs. This review aims exploring underlying mechanism providing possible practical strategies, methodologies insights to tackle these issues. First, this summarizes approaches achieving densities EFCs, particularly, employing enzyme cascades deep/complete oxidation fuels.

Diabetes affects millions of people worldwide and the number diagnoses continues to climb annually. Though several effective medications therapeutic methods have been developed treat type 1 (T1DM) 2 (T2DM) diabetes mellitus, direct insulin injection remains only treatment for resistant (IR) patients. Here, we immobilize in a crystalline mesoporous metal-organic framework (MOF), NU-1000, obtain high loading ∼40 wt % 30 min. The acid-stable MOF capsules are found effectively prevent from degrading presence stomach acid digestive enzyme, pepsin. Furthermore, encapsulated can be released NU-1000 under simulated physiological conditions.
