摘要：
In this communication, biosynthesis of gold nanoparticles assisted by Escherichia coli DH5 alpha and its application on direct electrochemistry of hemoglobin are reported. The gold nanoparticles formed on the bacteria surface are mostly spherical. The direct electrochemistry of hemoglobin can be achieved by incorporated into the bio-nanocomposite films on a glassy carbon electrode. (c) 2007 Elsevier B.V. All rights reserved.
