Melamine can be sensitively detected in aqueous medium through its selective interaction with polythymine (polyT(n)) modified gold nanoparticles (AuNPs) by forming triple H-bonds, which results in aggregation of the polyT(n)-stabilized AuNPs, displaying variations of localized plasmon resonance features such as colour change from red to purple and enhanced localized surface plasmon resonance light scattering (LSPR-LS) signals.
三聚氰胺可以通过与多胸腺嘧啶核苷（polyT(n)）修饰的金纳米粒子（AuNPs）的选择性相互作用在水相中被灵敏地检测到，形成三重氢键，导致polyT(n)稳定的 AuNPs 聚集，显示局部等离子体共振特征的变化，如颜色从红色变为紫色，以及增强的局部表面等离子体共振光散射（LSPR-LS）信号。
