Synthesis of microcapsules with encapsulated magnetic nanoparticles for α-amylase immobilization

Abstract

Polymeric microcapsules with paraffin core containing magnetite nanoparticles modified by oleic acid and functional polymeric shell were synthesized using the technique of "extraction-coacervation" microencapsulation. The influence of process parameters onto colloidal chemical properties (size, dispersity index, surface porosity) of synthesized microcapsules was studied. It was shown that the use of heterofunctional copolymer as microcapsule shell allows the possibility of irreversible immobilization of α- amylase and provide its participation in the reaction of starch catalytic decomposition.
