Abstract

Single-strand DNA chains were chemically grafted onto aligned carbon nanotube electrodes, leading to novel aligned carbon nanotube-DNA sensors of a high sensitivity and selectivity for probing complementary DNA and target DNA chains of specific sequences.

摘要

单链DNA链被化学接枝到排列好的碳纳米管电极上，从而产生了新型的排列好的碳纳米管-DNA传感器，该传感器对探测特定序列的互补DNA和靶DNA链具有高灵敏度和选择性。
