Macrocyclic Metal Complex–DNA Conjugates for Electrochemical Sensing of Single Nucleobase Changes in DNA
The direct incorporation
of macrocyclic cyclidene complexes into
DNA via automated synthesis results in a new family of metal-functionalized
DNA derivatives that readily demonstrate their utility through the
ability of one redox-active copperÂ(II)-containing strand to distinguish
electrochemically between all four canonical DNA nucleobases at a
single site within a target sequence of DNA
A Selective Blocking Method To Control the Overgrowth of Pt on Au Nanorods
A method
for the preparation of smooth deposits of Pt on Au nanorods
is described, involving sequential deposition steps with selective
blocking of surface sites that reduces Pt-on-Pt deposition. The Au–Pt
nanorods prepared by this method have higher long-term stability than
those prepared by standard Pt deposition. Electrochemical data show
that the resulting structure has more extended regions of Pt surface
and enhanced activity toward the carbon monoxide oxidation and oxygen
reduction reactions
