Objective To study how to use the leaky surface acoustic wave (LSAW) biosensor to detect single nucleotide polymorphism (SNP). Methods Two target sequences with a base difference (A/G) were added onto the LSAW biosensor reaction system and hybridized with corresponding probes. The enzyme signal amplification system was used in combination with single base extension (SBE) technology to observe changes in hybridization signals. Results The corresponding phase of targets was decreased to 6.47°±0.42° and 0.77°±0.25°
respectively
when the target point completely matched A and mismatched G (P<0.01). Conclusion A new method for the detection of SNP with a LSAW biosensor has been successfully established.
