title: Rapid naked-eye detection of mercury ions based on non-crosslinking aggregation of double-stranded DNA-carrying gold nanoparticles.
abstract: Colorimetric detection of mercury ions (Hg(2+)) with the naked eye was accomplished within 1 min by a combination of non-crosslinking aggregation of double-stranded DNA-carrying gold nanoparticles and complex formation of thymine-Hg(2+)-thymine.
