A biosensor based on a G-triplex DNA structure was developed for Hg2+ detection and validated in spiked milk samples. The sensor uses the T-Hg2+-T coordination chemistry that stabilises the G-triplex structure as the Hg2+ recognition mechanism. No unspiked occurrence measurements of Hg in milk are reported; validation is by spike-recovery in milk matrix.
Key numbers
- LOD, linear range, and recovery in spiked milk in full paper.
- No occurrence data for Hg in milk; all milk tests are spiked.
Methods (brief)
G-triplex DNA biosensor exploiting T-Hg2+-T coordination. Measures total inorganic Hg2+; does not distinguish methylmercury. Milk matrix spike-recovery validation.
Implications
Certification: Method development; milk matrix validation demonstrates analytical feasibility but provides no baseline Hg occurrence data for dairy. Courses: Demonstrates G-triplex DNA biosensor design exploiting specific Hg-DNA coordination chemistry.
