Colorimetric Detection of Sudan Based on the Aptamer and Cationic Compound Induced Gold Nanoparticles Aggregation
In this study, a simple, economical and rapid colorimetric assay was developed for the detection of Sudan, in which Sudan-binding aptamer was used as recognition element, unmodified gold nanoparticles (AuNPs) as sensing signal, and poly(diallyldimethylammonium chloride) (PDDA) as inducer for gold na...
