摘要: Abstract A novel, biocompatible sensing strategy based on graphene and chitosan composite film for immobilizing the hemoglobin protein was firstly adopted. The direct electron transfer bioelectrocatalytic activity of after incorporation into were investigated. pair reversible redox waves appeared, could exhibit its toward H2O2 in a long term. Such results indicated that be friendly interface biomolecules keeping their native structure. Furthermore, appearance facilitate between matrix electroactive center hemoglobin. Hence, this protocol would promising platform immobilization biosensor preparation.
