Abstract
PNA has demonstrated remarkable hybridization properties towards complementary oligonucleotides. In this paper, we tested the PNA's ability of selectively discriminating against single-base mismatches. Efforts were paid to optimizing the fabrication of PNA biosensors and its hybridization to achieve better discriminating capacity. Different factors were studied such as immobilization concentration, target concentration, ion strength and hybridization temperature. An optimized procedure was produced to reliably detect DNAs with single-base mismatches in the sequences. We synthesized two 16 mer PNAs with single-base mismatch to hybridizing with complementary DNA. The complementary PNA showed 8.6 fold stronger signal intensity than mismatch one under our optimized procedure.
