differential pulse voltammetry at CPE in the presence of SDS.We used
SDS for improving the sensitivity of the determination of BPR. The results
of the present study demonstrated that thismethod is valid for the measurement
of BPR in clinical samples. Themethod shown here has a great
potential for recognizing a rapid, accurate, and lowcost technique of BPR
determination. Also, two linear dynamic ranges, nanomolar detection
limit and good sensitivity, were the other advantages of this technique.
