In vitro detection of superoxide anions released from cancer cells based on potassium-doped carbon nanotubes-ionic liquid composite gels.

本文报道了一种基于钾掺杂多壁碳纳米管（KMWNTs）与1-丁基-3-甲基咪唑鎓六氟磷酸盐（[BMIM]PF6）离子液体复合凝胶的电化学生物传感器，用于检测癌细胞释放的超氧阴离子（O2•−）。KMWNTs–[BMIM]PF6凝胶在中性溶液中可电催化氧还原，产生强电流信号；与未加[BMIM]PF6的KMWNTs或MWNTs–[BMIM]...
