Abstract
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 μg L(-1) MA.
摘要
纳米银被适配体（ssDNA）修饰，得到用于三聚氰胺（MA）的共振散射（RS）探针（AgssDNA）。基于探针对费林粒子反应的催化作用，提出了一种纳米催化 RS 测定法，用于测定 0.02-1.06μg L(-1) 的 MA。
