Abstract
Disclosed are a selective colorimetric detection sensor and a colorimetric detection method for Cions using size controlled label-free gold nanoparticles, which may be useful for the detection of toxic materials such as heavy metal ions in the environmental sector and the industry. Selective colorimetric sensor solution used therein is selectively reacted with only Crions in trivalent chromium ions (Cr) and hexavalent chromium ions (Cr), and there is no interference effect resulting from other metal ions, and it is possible to very rapidly and precisely detect Crions compared to the related art.
