title: Simple and rapid colorimetric sensing of enzymatic cleavage and oxidative damage of single-stranded DNA with unmodified gold nanoparticles as indicator.
abstract: The sequence-length-dependent adsorption of single-stranded DNA (ssDNA) on unmodified gold nanoparticles is exploited as a new mechanism for colorimetric nuclease assay and measurement of oxidative DNA damage.
