title: Au@Ag core/shell nanoparticles as colorimetric probes for cyanide sensing.
abstract: We synthesize Au@Ag core/shell nanoparticles (NPs) using a Au NP assisted Tollens reaction. The as-synthesized NPs are used for the colorimetric cyanide sensing with a detection limit of 0.4 μM. The bimetallic NPs are immobilized into agarose gels as portable "test strips".
