Multi-drug resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) cause nosocomial infections that can have deleterious effects on human health. Thus, it is imperative to find solutions treat these detrimental well control their spread. We tested the effect of two different antimicrobial materials, functionalised graphene oxide (GOX), and AGXX® coated cellulose fibres, g...

This paper describes the development of a novel glucose biosensor through layer-by-layer technique (LbL). The self-assembled architectures were composed positive-charged silsesquioxane polyelectrolyte, 3-n-propylpyridinium chloride (SiPy+Cl−), nickel (II) tetrassulphophthalocyanine (NiTsPc), and conductive surface FTO (fluor tin oxide). construction was influenced by isoelectric point (pI) oxid...

Microporous glass ceramic with skeleton of CaTi4(PO¬4)6 with average pore size of 12.7 nm has been synthesized and used as a carrier of glucose oxidase. The glass ceramic was prepared by controlled heat treatment of glass samples, which causes the phase separation in their structure and creates CaTi4(PO¬4)6 and β-Ca3(PO4)2 phases. The β-Ca3(PO4)2 phase was dissolved by soaking the glass ceramic...

Background and Aim: This research aims to study the qualitative melissopalynology analysis, Glucose oxydase (GOX) activity, and the antibacterial effect of honey samples from different botanical and geographical origins. Materials and Methods: Five natural honey samples were collected from local beekeepers. The antibacterial effect was carried out towards pathogenic bacteria including Escheric...

Immobilisation of horseradish peroxidase (HRP) and glucose oxidase (GOX) via covalent attachment of modified enzyme carbohydrate to the exterior of the cowpea mosaic virus (CPMV) capsid gave high retention of enzymatic activity. The number of enzymes bound per virus was determined to be about eleven for HRP and 2-3 for GOX. This illustrates that relatively large biomacromolecules can be readily...

Amperometric glucose biosensors were constructed by codeposition of glucose oxidase (GOx) with chitosangold (chitosan-AuNP) on gold-Prussian Blue (Au-PB) nanoparticles modified glassy carbon electrodes (GCE). The high stability of the biosensors was achieved using electrochemically controllable in situ Au-PB film preparation following the film covering with GOx layer encrusted with chitosan-AuN...

Glucose oxidase (GOx) is an enzyme frequently used in glucose biosensors. As increased temperatures can enhance the performance of electrochemical sensors, we investigated impact temperature pulses on GOx that was drop-coated flattened Pt microwires. The wires were heated by alternating current. sensitivity towards and stability amperometry. An up to 22-fold increase observed. Spatially resolve...

We report here on a facile enzymatic polymerization protocol to prepare enzyme-poly(thiophene-3-boronic acid) (PTBA) polymeric biocomposites (PBCs) for high-performance mono-/bi-enzyme amperometric biosensing. Horseradish peroxidase (HRP)-catalyzed polymerization of thiophene-3-boronic acid (TBA) monomer was conducted in aqueous solution containing HRP (or plus glucose oxidase (GOx)) by either ...

A simple colorimetric assay for blood glucose has been developed based on enzymatic engineering of gold nanorods by glucose oxidase (GOx)-mediated oxidative etching of gold nanorods.

A simple, mild and convenient method has been developed for catalytic immobilisation of glucose oxidase (GOx), chemically modified to contain pendant methallylsilyl groups, on an untreated silica surface.
