采用核酸适体（ssDNA）修饰纳米银，制备了三聚氰胺（MA）的共振散射（RS）探针（AgssDNA）。基于Fehling粒子反应的探针的催化作用，提出了一种纳米催化RS测定0.02-1.06 μ g L-1 MA。
Nanosilver was modified by aptamer (ssDNA) to obtain a resonance scattering (RS) probe (AgssDNA) for melamine (MA). Based on the catalytic effect of the probe on the Fehling particle reaction, a nanocatalytic RS assay is proposed for the determination of 0.02-1.06 mu g L-1 MA.
