摘要: In the recent years, increasing interests are being focused on rational functionalization of CNTs by some creative methods. However, considerable toxicity CNT is still a controversialissue and limits its biological application. To improve biocompatibility CNT, in this work we prepared CNT- nanocomposites with organic titanium precursors. Our observations demonstratethat modified interface could accelerate heterogeneous electron transfer rates thusenhance relevant detection sensitivity, suggesting potential application as new strategy for development biocompatible multi-signal responsive biosensors early diagnosis cancers.
