Polymer nanocomposites containing nanometals became a subject of interest due to their bactericidal properties. Different polysaccharides have been used as matrices for nanosilver and nanogold synthesis. In this study, we present novel, environmentally friendly method the preparation sodium alginate/nanosilver/graphene oxide (GOX) alginate/nanogold/graphene GOX characteristics. The formation ap...

Rapid and accurate detection of glucose is great significance for diabetic management. Highly sensitive sensors promise to achieve noninvasive technology, enabling more convenient efficient means large-scale screening long-term dynamic monitoring diabetes patients. In this work, we demonstrate a electrochemical biosensor through the synergetic labelling strategy utilizing PbS colloidal quantum ...

Using glucose oxidase (GOx) as a target protein, we studied the adsorption of protein on the phenothiazine-modified electrodes and assessed the potential of using the electrodes in biochemical applications. Experiment results showed that thionine chloride (TC) and its structural analogues, such as toluidine blue and methylene blue, fluoresced under photochemical excitation after being immobiliz...

We developed a simple high-throughput colorimetric assay to detect glucose based on the glucose oxidase (GOx)-catalysed enlargement of gold nanoparticles (AuNPs). Compared with the currently available glucose kit method, the AuNP-based assay provides higher clinical sensitivity at lower cost, indicating its great potential to be a powerful tool for clinical screening of glucose.

Neuroblastoma cells can acquire resistance mechanisms that make them invulnerable to chemotherapeutic agents. The use of nanoparticles as drug carriers provides the possibility deliver several drugs simultaneously specific tumoral cell populations, improving their therapeutic outcome. Herein, development a multifunctional nanoplatform based on assembly protocells (PC) and polymeric nanocapsules...

The interface between silicon carbide (SiC) and dioxide (SiO2) is of considerable importance for the performance reliability 4H-SiC (trench) metal oxide semiconductor field effect transistors (MOSFETs) various different post oxidation anneals (POAs) have been used to optimize its quality. Whereas nitric (NO) POA leads very reliable well performing MOSFETs, ammonia (NH3) can further improve devi...

The microbial fuel cell (MFC) is an ecologically friendly alternative energy source. Due to the typically limited electron transfer in MFC systems, co-biocatalysts are necessary enhance their performance. Enzymes used as due superior ability generate energy, and system known enzymatic (EMFC). One of substrates that may be bagasse waste extracted from sugarcane. Saccharo­myces cerevisiae enzyme ...

Here, we demonstrate a strategy to convert the graded Michaelis-Menten response typical of unregulated enzymes into a sharp, effectively all-or-none response. We do so using an approach analogous to the "branch point effect", a mechanism observed in naturally occurring metabolic networks in which two or more enzymes compete for the same substrate. As a model system, we used the enzymatic reacti...

A novel, sensitive chemiluminescence (CL) immunoassay for Escherichia coli O157:H7 detection with signal dual-amplification using glucose oxidase (GOx) and laccase was investigated. The method was based on the characterization of a luminol-H2O2-laccase reaction. Compared with the horseradish peroxidase-based biosensor, laccase exhibited high catalytic activity in strong alkaline medium, which w...
