Abstract

SERS biosensor for sensitive and selective detection of lead ions (Pb 2+) based on DNAzyme was developed by taking advantage of the specific catalytic reaction of DNAzyme upon binding to Pb2+ ions. Detection was accomplished by SERS nanoprobe labeled with DNA and Raman reporters for signal amplification.
