Functionalized polyacetylenes with strong luminescence: “turn-on” fluorescent detection of cyanide based on the dissolution of gold nanoparticles and its application in real samples

Abstract

By dissolution of Au NPs, new polyacetylene-functionalized Au NPs were successfully developed as “turn-on” fluorescent probes for the detection of cyanide sensitively and selectively. The lowest concentration to quantify cyanide ions could be down to 3.0 × 10−6 M, and other common anions including AcO, Br, C2O42, Cl, CO32, F, HCO3, NO2, NO3, PO43, S2O82, SCN, SO32, SO42, HPO42, and P2O74 had almost no influence. Furthermore, several real water samples spiked with cyanide, including local groundwater, tap water, boiled water, and lake water, were analyzed with RSD values less than 4%, and the experimental results demonstrated that our developed sensing system worked well in the above water samples.
