Boron Carbon Nitride Nanosheets-Ru Nanocomposite Self-Enhancement Electrochemiluminescence Emitter with a Three-Dimensional DNA Network Structure as a Signal Amplifier for Ultrasensitive Detection of TK1 mRNA.

本研究通过氮化硼碳纳米片（BCN NSs）与三(4,4'-二羧酸-2,2'-联吡啶)钌(II)二氯化物（Ru(dcbpy)3Cl2）化学交联，制备了自增强纳米复合材料BCN NSs-Ru，并将其作为发射体构建电化学发光（ECL）生物传感器，用于超灵敏检测癌症标志物人胸苷激酶1（TK1）mRNA。BCN NSs边缘的氨基和不饱和硼原子...
