英文摘要Mercury ion, as a highly hazardous heavy metal ion, can be easily ingested by humans via the aquatic products and water intake, and more worrying than that is the risk that the accumulation of Hg2+ in the body tissues is eliminated slowly, posing a grave threat to human health. Herein, a novel nano-silver hybrid material (CSWCNTs-PE-Ag) with oxidase-like activity was successfully fabricated to conduct a rapid detection of Hg2+ in aquatic products, which consists of the carboxylated single-walled carbon nanotubes grafted on the analytical grade Cryptophyte phycoerythrin 566 (Cr-PE566) and in-situ synthesis of nano-silver with the face-centered cubic crystal structure. By introducing Hg2+, the enhancement of catalytic activities of the hybrid material causes an oxidation of 3,3 ',5,5 '-tetramethylbenzidine (TMB) by yielding more superoxide anions (O2 center dot-) and a subsequent concentration-dependent color change, which offers new avenues for developing a CSWCNTs-PE-Ag / TMB colorimetric sensing platform to achieve the quantitative detection of the concentration of Hg2+. Under the optimized conditions, for this sensing platform, the detection limit reach as low as 100 nM and the linear range was found to be between 5 and 100 mu M. Moreover, a negligible interference from potential interferents common in aquatic tissues exhibited the high specificity of the constructed sensing platform, proving to be suitable for the practical detection of oysters, clams, and river shrimps. Our study proposes a valuable alternative for the expeditious quantitative detection of mercury ions, which hold considerable application prospects in the contamination detection of real aquatic products.
