Facile Interfacial Electron Transfer of Hemoglobin

Facile Interfacial Electron Transfer of Hemoglobin

Abstract: We herein describe a method of depositing hemoglobin (Hb) and sulfonated polyaniline (SPAN) on GC electrodes that facilitate interfacial protein electron transfer. Well-defined, reproducible, chemically reversible peaks of Hb and SPAN can be obtained in our experiments. We also observed en...
