Rare Self-Luminous Mixed-Valence Eu-MOF with a Self-Enhanced Characteristic as a Near-Infrared Fluorescent ECL Probe for Nondestructive Immunodetection.

本文报道了一种基于稀有混合价 Eu-MOF（L4EuIII2EuII）的近红外（NIR）电化学发光（ECL）生物传感器，用于 CYFRA 21-1 的无损免疫检测。由于 Eu2+ 与 Eu3+ 离子半径和核外电子构型相近，L4EuIII2EuII 中可实现稳定高效的 Eu2+ 到 Eu3+ 敏化发光，从而增强自发光、延长发光时间并提...
