Direct Electrochemical DNA Sensor based on a new redox oligomer modified with ferrocene and carboxylic acid: Application to the detection of Mycobacterium tuberculosis mutant strain.
本文合成了一种新型氧化还原低聚物“oligo-methoxy-phenyl-acetonitrile”(Fc-acid-OMPA),其侧链同时引入二茂铁(Fc)基团和羧酸官能团。该氧化还原指示剂可用于监测电化学行为,羧酸官能团为生物分子的直接共价连接提供灵活性。通过循环伏安法研究沉积在金电极上的低聚物膜,得到电子转移速率 6.43 ...
