The Effects of Organic Solvents on Catalytic Behavior of Immobilized Hemoglobin Nanocomposites: Functional Groups and Molecular Constitution

Article Preview

Abstract:

The use of organic solvents as reaction media for enzymatic reactions provides numerous industrially attractive advantages compared to traditional aqueous reaction systems. Hemoglobin (Hb) intercalated magadiite nano-composites was successfully prepared by exfoliation-reassembly method at room temperature and pH=7, and was used to catalyze the oxidation of o-phenylenediamine in organic solvents. Catalytic activity of immobilized Hb in organic solvents with different hydrophobicity and different functional groups were investigated detailedly. The results showed that functional groups and molecular constitution of the organic solvents were both important factors to determine catalytic activity of immobilized Hb in organic media except hydrophobicity of organic solvents.
