The vertically aligned carbon nanotubes arrays as biointerface for the E. Coli strain M-17

Abstract

Abstract The biological interaction materials study is necessary when creating biocompatible implantable devices, including biosensors. Important criteria for their creation are the bactericidal properties of such materials. In this paper, we study the bacteria with vertically aligned carbon nanotubes interaction. In this work we examined the bioaffinity of multi-walled carbon nanotubes samples with E. Coli strain M17 bacteria. We synthesized carbon nanotubes with various structural features on the surface of silicon wafers. Then westudied of the wettability of the obtained samples and tested bioactivity of E. Coli bacteria using spectrometry and photometry methods. It was found that E. Coli bacteria of strain M-17 demonstrated the best vital signs when interacting with the surfaces of hydrophobic samples of vertically oriented carbon nanotubes.
