In order to safeguard the food safety and security of the consumer, a rapid and sensitive detection method for bacteria pathogen has been demanded. An electrochemical biosensor for bacteria (Escherichia coli K12) was being developed in this research. This report presents the synthesis, surface modification of Fe3O4 nanoparticles (Fe3O4 NPs), conjugation of Fe3O4 nanoparticles with rabbit antibodies, immuno-magnetic separation for Escherichia coli K12 (E. coli) and the bacteria detection through electrochemical measurement.
