Abstract
Facile regulation and enhancing of the performance of bioimmobilization materials is a key factor for their applications for biosensing, biocatalysis, bioreactor, and so on. Here, we propose a method of combined polymerizations of chemical oxidation and metal organic coordination to develop enhanced bioimmobilization matrices for high performance biosensing. Being different from conventional methods that are based on sole polymerization, the new method elaborated chemical oxidation to one-pot obtain oligomers as ligands for metal–organic coordination polymerization. Two kinds of thiol that could be chemically oxidized by H2O2 and be coordinated with NaAuCl4 were adopted as monomers. Glucose oxidase was adopted as the representative biomolecule. Chemical oxidation was proved to be efficient to lengthen monomers to produce oligomers (ligands) with different lengths by adjusting the concentrations of monomers and oxidant, as well as reaction time. This dynamic prelengthening process not only endows the coexi...

To conveniently obtain one-dimensional MnO2 nanowires (NWs) with controlled structure and unique properties for electron transfer, the genetically engineered M13 phages were used as templates for precise nucleation and growth of MnO2 crystals in filamentous phage scaffolds, via the spontaneous oxidation of Mn2+ in alkaline solution. It was found that the morphology of NWs could be tailored by the surface charge of M13 mutants. MnO2 crystals were uniformly distributed on the surface of negatively...

A highly luminescent and water-stable homochiral Zn-MOF, i.e., Zn-PLA, has been developed based on a pyrene-tetralactic acid, which inherently features concave shapes for guest inclusion, to explore sensing of amino acids by fluorescence quenching; the solid-state fluorescence quantum yield of the MOF was found to be 46%. The fluorescence of an aqueous suspension of Zn-PLA was shown to be quenched specifically by histidine amongst all the other amino acids. Selective sensing of histidine is of p...

Metal–Organic Frameworks (MOFs) are porous crystalline materials that have emerged as promising hosts for the heterogenization of homogeneous organometallic catalysts, forming hybrid materials which combine the benefits of both classes of catalysts. Herein, we report the encapsulation of the organometallic cationic Lewis acidic catalyst [CpFe(CO)2(L)]+ ([Fp–L]+, Cp = η5-C5H5, L = weakly bound solvent) inside the pores of the anionic [Et4N]3[In3(BTC)4] MOF (H3BTC = benzenetricarboxylic acid) via ...

In this work, self-assembled NiFe2O4/carbon nanotubes (CNTs) sponge was prepared by ice-templating method. The device synergized the advantageous features of both the 3D porous nanostructure and the catalytic properties of CNTs with GOx and NiFe2O4 nanoparticles. The porous network construction of the NiFe2O4/CNTs sheets offered enlarged specific surface for GOx immobilization and opened channels for facilitating the electrons transport and reactants diffusion. With the help of the abnormal-vale...

Nitrogen and sulfur codoped carbon-based dots (N,S-CDs) with strong blue light emission are encapsulated into red light-emitting europium metal–organic frameworks (Eu-MOFs) to form two color light-emitting nanohybrids (Eu-MOFs/N,S-CDs). In organic solvents, the encapsulated N,S-CDs are aggregated and confined in the cavities of the Eu-MOFs, exhibiting only a very weak photoluminescence (PL) signal. Therefore, the nanohybrids show red light emission of the Eu-MOFs. Contrarily, when the Eu-MOFs/N,...

Abstract To increase the protein capability and simplify biosensing fabrication, a three-dimensional (3D) nitrogen-doped carbon nanotubes (NCNTs) on free-standing electrospun carbon nanofibers film (NCNT@CNFs) was prepared via pyrolysis of pyridine. The density, size and nitrogen content of the “quasi-aligned” NCNT arrays can be easily controlled by modulating the growth temperature. By directly dropping the free-standing and flexible composite onto the electrode surface with high glucose oxidas...

The separation of high purity ethene from the mixed gaseous products of cracking poses significant obstacles. Here, the authors present a metal-organic framework which, in contrast to most absorbents, selectively binds the less polar ethane thus allowing the efficient collection of the target product.

Abstract Due to the fragile nature but the irreplaceable role of proteins as analytical tools, the preservation of proteins to minimize their activity and functionality loss is an essential issue for analytical applications. The hybridization of proteins and nanomaterials (protein-nanomaterial hybrids, PN hybrids) integrates diversified merits of proteins and nanomaterials and even shows synergy effects, has paved a new way of significant prospects of protein preservation for storage and operati...

Abstract Inspired by biomineralization, we propose robust enzyme-metal-organic-frameworks (MOFs) biocomposites to fabricate ultra-stable modified-electrode for electrochemical biosensing. Glucose oxidase (GOx) and zeolitic imidazolate framework-8 (ZIF-8) were adopted as model enzyme and MOFs to illustrate and examine the proposed concept. The biocomposites could be readily prepared by mixing GOx and precursors of MOFs. The biomineralization-assisted in-situ entrapment method facilitated the form...
