The colorimetric detection sensor and colorimetric detection method use label-free nanorods having no modifier attached to a surface of gold nanorods (AuNRs), wherein the aspect ratio of nanorods, pH condition and/or amount of a surfactant are controlled to carry out selective etching and to cause a change in color only by CN− so that CN− contained or dissolved in poison, water-contaminated environmental samples and legal evidence samples may be detected with ease, and show excellent selectivity, sensitivity and quantitative analyzability to CN− to provide high usefulness."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Colorimetric detection sensor and colorimetric detection method for detecting cyanide anion by etching of gold nanorods","description":"Disclosed are a colorimetric detection sensor and colorimetric detection method of a cyanide anion (CN−) by etching of gold nanorods.
