具有异常高的亲和力的铅（II）离子与凝血酶结合适体的结合导致共振瑞利散射（RRS）的增强。本文提出了一种简便、灵敏、选择性好的直接测定痕量Pb ~（2+）的方法。
The binding of lead(II) ions with unusually high affinity to a thrombin binding aptamer resulted in an enhancement of resonance Rayleigh scattering (RRS). A simple, sensitive, and selective assay for the direct determination of trace amounts of Pb2+ on the basis of RRS has been proposed.
