Detection capacity of the graphite felt electrode. (a) Current response generated by the graphite felt electrode using a fixed concentration of capture antibody and various levels of conjugate (10−9 to 10−13). (b) Current response generated by various amounts of capture antibody (10−9 to 10−13) and a fixed concentration of conjugate. Bars represent the average current response generated for each of the four trials with the error bars representing one standard deviation of the mean. Significance between measured electric current signals is noted by different letters as determined by Student’s t test at a 95% confidence level
