Enhancing laccase stability and activity for dyes decolorization using ZIF-8@MWCNT nanocomposite

Enzyme-Immobilized Porous Crystals for Environmental Applications

“…This feature effectively shields enzymes from external environmental influences to some extent, thereby enhancing their stability. MOF−enzyme composites, particularly those involving ZIF-8, have found widespread application in the degradation of industrial dyes, 53 phenolic compounds, 54 and pesticides. 55 Regrettably, the ZIF-8 shell presents a limitation with its narrow aperture (3.4 Å), significantly impeding the diffusion of organic pollutants and consequently slowing down pollutant degradation.…”

An electrochemical ratiometric immunosensor for the detection of NMP22 based on ZIF-8@MWCNTs@Chit@Fc@AuNPs and AuPt-MB

“…The change in the pH value was able to cause a change in the current due to the fact that immobilized biomolecules are easy to deactivate in an overly acidic or alkaline environment. 42 Therefore, the pH value of PBS was 7.0. The concentration of NMP22-Ab 1 can affect the…”

Enzyme Immobilization using Covalent Organic Frameworks: From Synthetic Strategy to COFs Functional Role

“…They also have diverse and unique chemical/structural designs, including functional diversity on the metal nodes or organic ligands and high designability in the immobilization process. These qualities make them appropriate platforms for the immobilization of enzymes. − However, the practical application of MOF supports is currently limited by the potential for toxic metal ion leaching, as well as suboptimal long-term chemical and water stability, while for HOF carriers, their relatively weak bonds likely hinder long-term stability and reusability. − In contrast, COFs are constructed from metal-free organic building units and are ligated by strong covalent bonds. Their finely tunable pore environments, long-term structural stability, and metal-free skeletons make COFs attractive platforms for enzyme immobilization. − Nevertheless, adverse conditions in COF synthetic processes, characterized by high temperatures and organic solvents, limit the availability and efficacy of strategies for enzyme immobilization.…”
