The magnetically recoverable biocatalyst was developed. The catalyst support is based on magnetite particles (MPs) composed of magnetite particles and coated with the amino terminated silica layer to facilitate further functionalization. This functionalization involves the attachment of the glutaraldehyde linker followed by the covalent attachment of horseradish peroxidase (HRP) via its amino groups. The catalyst was tested in the reaction of 2,3,6-trimethylphenol (TMP) oxidation to 2,3,5-trimethylhydrochinone (TM...

Here, we developed an effective D-glucose oxidation with magnetically recoverable biocatalysts. These biocatalysts were synthesized on magnetite particles obtained by different methods, polyol and co-precipitation. These MPs were coated with a layer of silica modified with amino groups. The GOx covalent attachment has been carried out via the reaction with glutaraldehyde. We established that the method of MPs synthesis affect the enzyme catalytic activity. It should be noted that the magnetically recoverable bioca...

The work described the obtaining and studying the properties of alginate-PLGA matrixes containing agglomerates of hydroxyapatite nanoparticles. Hydroxyapatite (HAP) nanoparticles were obtained by controlled deposition in the presence of a stabilizer - sodium citrate. Two types of nanoparticle lamellar (30 to 50 nm in size) and rod-shaped (150 to 200 nm in length) were used in the work. The size and morphology of the hydroxyapatite nanoparticles were studied using a transmission electron microscope. The composition...
