Enzyme-functionalised, core/shell magnetic nanoparticles for selective pH-triggered sucrose capture.

ABSTRACT: Diabetes is a chronic metabolic disease which leads to high glucose levels in the blood, with severe consequences for human health. Due to the worldwide appeal for the reduction in calorie intake, this study presents the development of a nanomaterial able to capture sucrose selectively, thus providing a tool to remove naturally occurring sucrose from food, such as fruit juices, producing low-calorie juices for consumption. Magnetite nanoparticles (Fe₃O₄ NPs) coated with an inert material (SiO₂) and functionalised with the enzyme invertase were designed to remove sucrose from solutions. Fe₃O₄ NPs were synthesised using the co-precipitation method, whereas the coating with a silica shell was done by the Stöber method. Its physicochemical
