Electrochemical detection of type 2 diabetes mellitus-related SNP via DNA-mediated growth of silver nanoparticles on single walled carbon nanotubes

Herein, we proposed a new electrochemical sensing strategy for T2DM-related SNP detection via DNA-mediated growth of AgNPs on a SWCNT-modified electrode. Coupled with RNase HII enzyme assisted amplification, this approach could realize T2DM-related SNP assay and be applied in crude extracts of carcinoma pancreatic β-cell lines.
