Abstract
This study developed a method of detecting bioparticles such as Salmonella that exist in the biological samples The method employed a substrate with interlaced comblike electrodes into which the mixtures of biological samples and antibodycoated gold nanoparticles were added The alternative signals with appropriate frequency bands were then conducted into the comblike electrodes to change the dielectrophoresis force The goldmodified Salmonella can be adsorbed on the edges of the electrodes and isolated from various biological samples The impedance of the adsorbed Salmonella on the edges of the electrodes was measured and comparison of the impedance between the electrodes with and without Salmonella can quantify the amount of the adsorbed Salmonella
