Abstract:
... The meso-molding three-dimensionally ordered macroporous alumina (3DOM/m-Al) was synthesized via a dual-templating approach (polystyrene (PS) colloidal crystals as hard template and triblock copolymer P123 as soft template) with hydrous aluminum isopropoxide as precursor. The obtained 3DOM/m-Al was characterized, and the results showed that 3DOM/m-Al had ordered macropores (ca. 300 nm in diameter) ...

Abstract:
... Hydrophobic virus-like organosilica nanoparticles (VOSNs) with a spherical core formed by mesoporous organosilica surrounded by epitaxial perpendicular nanotubes were successfully synthesized for the first time. These hydrophobic VOSNs were used for the immobilization of the lipase B from Candida antarctica (CALB) via covalent binding method, where glutaraldehyde was used as a spacer to form coval ...

Abstract:
... Tannic-acid-templated magnetic mesoporous silica nanoparticles (TA-MMSNs) were synthesized for the first time. The TA-MMSNs were monodisperse spherical particles with a diameter of around 250nm and a magnetization saturation value of 35.26 emu/g. The specific surface area of TA-MMSNs was 423.4m²/g, and the diameter and cumulative volume of the pores were 9.349nm and 1.071cm³/g, respectively. The T ...

Abstract:
... In this study, the magnetic combined cross-linked enzyme aggregates (combi-CLEAs) of glucose oxidase (GOD) and horseradish peroxidase (HRP) were designed and prepared successfully. The magnetic combi-CLEAs were fabricated by co-precipitation and cross-linking for the immobilization of GOD and HRP onto amino-functionalized Fe₃O₄ particles. Ethanol and glutaraldehyde were used as precipitant and cro ...

Abstract:
... Cross-linked enzyme aggregates (CLEAs) are a versatile and effective method for enzyme immobilization, which is exquisitely simple and amenable to rapid optimization. In this study, nature egg white, which is low cost, easily available, and nontoxic, was used as protein feeder to replace traditional protein feeder (bovine serum albumin, etc.) in the preparation of laccase CLEAs (CLEAs-egg). The ef ...
