In this work, a micron-sized flower-like metal–organic frameworks (MOFs)-based boronate-affinity sandwich-type immunoassay was fabricated for the dual-mode glycoprotein assay. For proof of concept, MOFs were synthesized from transition Cu nodes and tetrakis (4-carboxyphenyl) porphyrin (TCPP) ligands by spontaneous standing assembly. addition, specificity toward involved antigen recognition as well covalent bonding via boronate-glycan affinity, immediate signal responses initiated textural decomposition MOFs. Intriguingly, nodes, which valence state is dominant CuI species, can endow Fenton-like catalytic reaction fluorogenic substrate generating fluorescence signals. benefits, TCPP ligands, in each molecule has four guest donors, provide multiple valences assembly cyclodextrin-capped gold nanoparticles host–guest interaction colorimetry output. Albeit important, scaling micrometer patterns carrying numerous also function amplifying units, signifying output signal. The detection limit assay reach 10.5 nM mode 18.7 mode, respectively. Furthermore, merits harvesting different generators multimodal readout allow mutual verification make analytical results more reliable. Collectively, our proposed may offer new idea combining inherent dual generators, emphasize accurate capability

Enzymes, as highly efficient biocatalysts, excel in catalyzing diverse reactions with exceptional activity and selective properties under mild conditions. Nonetheless, their broad applications are hindered by inherent fragility, including low thermal stability, limited pH tolerance, sensitivity to organic solvents denaturants. Encapsulating enzymes within metal–organic frameworks (MOFs) can protect them from denaturation these harsh environments. However, this often leads a compromised enzyme activity. In recent years, extensive research efforts have been dedicated enhancing enzymatic MOFs, leading the development of new enzyme–MOF composites that not only preserve catalytic potential but also outperform free counterparts. This Review provides comprehensive review on developments specific emphasis enhanced compared enzymes.

Abstract Manipulating the electronic structure and coordination configuration of heterogeneous electrocatalyst is an advantageous strategy to motivate intrinsic activity but remains challenging. Herein, guided by theoretical mechanism d‐band center valence‐bond theory, high‐valence metal‐modulated nickel‐vanadium layered double hydroxides (M‐NiV LDH, M = Zr, Mo) with interfacial oxygen bridge bonding are rationally designed fabricated, affording a 3D vertically staggered porous nanosheets array network. Benefitting from abundant unfilled antibonding orbitals induced optimized Zr d‐orbital O p‐orbital hybridization, introduction site beneficial accelerate charge transfer kinetics optimize deprotonation OH* as well lower O* → OOH* free energy. As result, as‐prepared Zr‐NiV LDH exhibits promising evolution reaction performance low overpotential favorable long‐term stability. This work provides valuable insights into design electrocatalysts for regulation improvement.

However, the small apertures of restrict effectiveness to organic molecules. Herein, we present a green strategy directed by visible linker micelles aqueous synthesis MAF-6 that enables catalytic asymmetric chiral Due large pore aperture (7.6 Å), double size benchmark ZIF-8 (3.4 allows encapsulated enzyme BCL access larger substrates do so faster. Through optimization surfactants' effect during synthesis, BCL@MAF-6-SDS (SDS = sodium dodecyl sulfate) displayed efficiency (Kcat/Km) was 420 times greater than BCL@ZIF-8. This biocomposite efficiently catalyzed drug precursor molecules with 94–99% enantioselectivity nearly quantitative yields. These findings represent deeper understanding de novo synthetic encapsulation in MOFs, thereby unfolding great potential enzyme@MAF catalysts organics pharmaceuticals.

In situ drug synthesis using the copper-catalyzed azide–alkyne cycloaddition (CuAAC) reaction has attracted considerable attention in tumor therapy because of its satisfactory effectiveness and reduced side-effects. However, exogenous addition copper catalysts can cause cytotoxicity hampered biomedical applications vivo. Here, we design synthesize a metal–organic framework (MOF) to mimic chaperone, which selectively modulate trafficking for bioorthogonal with no need catalysts. Like chaperones, prepared ZIF-8 chaperone mimics specifically bind ions through formation coordination bonds. Moreover, is unloaded under acidic environment due dissipation interactions between metal ligands. this way, cancer cell-targeted transport into cells.

Enzymes are promising biocatalysts due to their high efficiency, mild conditions, specificity, nontoxicity, and environmental friendliness. However, the enzyme suffers from poor stability reusability. Enzyme immobilization is a commonly used technology enhance its In this study, cellulose nanocrystal (CNC) was chosen as carrier sustainability, specific surface area, biocompatibility, water dispersibility, excellent Pickering emulsifying ability. Lipase immobilized on polydopamine-coated CNC (PC), obtained lipase-immobilized PC (LPC) displayed significantly enhanced higher activity in harsh conditions compared free lipase. LPC possessed partial wettability with both oil phases lower absolute value of zeta potential than CNC, endowing it better ability CNC. fixed at oil–water interface emulsion by ultrasonication, resulting droplets were employed microreactors for ester hydrolysis synthesis via biocatalysis. catalysis lipase traditional biphasic system increased contact area between substrate, reduced diffusion distance activation effect.
