Patent Images
1. A method of detecting a mutation in a target DNA comprising:
- obtaining a first measurement of a resonance parameter of a resonator sensor, said resonator sensor having a vibrating element, said vibrating element having a surface, and a probe DNA immobilised on said surface, said probe DNA hybridized with a target DNA;
contacting the hybridized probe DNA and target DNA with a mismatch binding molecule;
obtaining a second measurement of the resonance parameter of the resonator sensor;
and comparing the first and second measurement of the resonance parameter.

Abstract
There is provided a resonator sensor useful for detecting polymorphisms and mutations in DNA. The resonator sensor has a capture molecule immobilised on its surface, the capture molecule being either a probe DNA containing a reference sequence, or a mismatch binding molecule, and being capable of forming a probe DNA/target DNA/mismatch binding molecule complex on the surface of the resonator. A method for detecting mutations in a target DNA, including single nucleotide polymorphisms, is also provided.
