摘要
We implement the progressive dilution strategy to bring assays based on gold nanoparticles to a quantitative level. This is demonstrated by the detection of adenosine in urine by combining progressive dilution with the silver enhancement of aptamer-gold nanoparticle aggregation, giving good accuracy, high selectivity, and an unlimited dynamic range above LOD.
