Detection of sub-femtomolar DNA based on double potential electrodeposition of electrocatalytic platinum nanoparticles. (2013)

Abstract Suspensions of electrocatalytic platinum nanoparticles with radii as small as 78.9 ± 3.5 nm that are functionalised with DNA only in one region have been created using templated electrodeposition. The integrity of the bound DNA following nanoparticle desorption from the electrode is demonstrated by detecting attomolar concentrations of DNA without the need for molecular, e.g., PCR or NASBA, amplification. Double potential step approaches coupled with interface engineering via nucleation sites allows PtNPs to be created with controlled particle size and density in a facile and reproducible manner.
