The strong catalytic performance, eco-friendly reaction systems, and selectivity of enzyme-based biocatalysts are extremely interesting. Immobilization has been shown to be a good way improve enzyme stability recyclability. Chitosan-incorporated metal oxides, among other support matrices, an intriguing class matrices for the immobilization various enzymes. Herein, cross-linked chitosan/zinc oxi...

Abstract Metal organic frameworks (MOFs) are multi-dimensional network of crystalline material held together by bonding metal atoms and ligands. Owing to unique structural, chemical, physical properties, MOFs has been used for enzyme immobilization be employed in different catalytic process, including degradation antibiotics. Immobilization process other than providing large surface provides wi...

In enzymatic devices, efforts have been concentrated on the control over enzyme activity, which is highly dependent on the interface between the electrode and the enzyme. Such con‐ trol has led to immobilization techniques suitable for anchoring the enzyme close to elec‐ trode with preservation of its biological activity. In these type of devices, where retaining of the enzyme activity at the e...

The determination of creatinine levels in biological fluids is an increasingly important clinical requirement. Amperometric biosensors have been developed based on a three-enzyme system which converts creatinine to amperometrically measurable hydrogen peroxide. The development of the amperometric creatinine biosensor has been slow due the complexity of the three-enzyme system. This paper, the f...
