Efficient cyanide sensing using plasmonic Ag/Fe₃O₄ nanoparticles.

ABSTRACT: In the line of our previous studies, we have reported a developed sensitive and selective probe for cyanide detection based on Ag/Fe₃O₄ nanoparticles (NPs) with an extremely low limit of detection at the level of ng per milliliter. Herein, we report the improvement of the easy-to-make magnetic silver nanoparticle-based sensor system for cyanide determination in an extended calibration range with higher selectivity and precision. As far as our knowledge is concerned, the detectable linear range from 1.0 nM to 160 μM (0.026 ng mL^-1 to 4.16 μg mL^-1) of the improved simple highly precise technique represents the widest assay that has been reported so far. The method is based on strong enhancement of scattered light of the plasmonic nanoparticles and
