Development of Gold Nanoparticle-Based Rapid Detection Kit for Melamine in Milk Products

Abstract: A reliable and sensitive kit for the rapid detection of melamine (Mel) was developed. The kit is based on gold nanoparticle (Au NP) probe and includes a standard colorimetric card. The Au NPs were prepared by sodium borohydride reduction and characterized by transmission electron microscopy, which revealed particle sizes of approximately 5 nm. The performance of the kit in terms of aggregation kinetics, cross-reactivity, anti-interference, and sample pretreatment was investigated. The standard colorimetric car… Show more

“…MA was detected using AuNPs with a LOD 0.4 mg/L displayed in 12 min including sample preparation [63]. The developed gold nanoparticle-based kit for MA detection in milk products reached working range of 1-120 mg/l improving time of detection about 10 min including sample pretreatment [64]. However, Cao et al found that hydrogen-bonding can induce colorimetric detection of MA by label free, and nonaggregation-based AuNPs probe prepared using 3,5-dihydroxybenzoic acid (DBA) reducer interact with MA through strong hydrogen-bonding interaction.…”

“…The chemical became a global concern in 2008 because a high amount of melamine had been illegally added to pet food and even infant milk formula in China [1,2]. The long-term ingestion of melamine may cause severe damages like kidney stones [3], bladder stones [4,5], and even bladder cancer [6,7].…”
