Abstract
⺠A novel label-free potassium ions (K+) fluorescent aptasensor was developed. ⺠A single stranded G-rich DNA (ssDNA) was used as the recognition element for K+. ⺠The employed DNA specifically interacts with K+ and hemin to form a DNAzyme. ⺠H2O2-mediated oxidation of 3-(p-Hydroxyphenyl)-propanoic is accelerated by the DNAzyme. ⺠The proposed aptasensor is of high selectivity and sensitivity for K+ detection.
