The structure of multi-walled carbon nanotubes as a factor affecting the life of E. Coli

Abstract

In this work, we investigated the relationship between the structural properties of materials based on multi-walled carbon nanotubes and the vital activity of bacteria E. Coli strain M-17. In the course of research using scanning electron microscopy and Raman spectroscopy, the structure of nanotubes was analyzed. Nanotube samples were tested for wettability. The effect of carbon nanotube samples on the growth of the bacterial culture of E. Coli strain M-17 using spectrophotometry was investigated. As a result, it was shown that samples containing more disordered defective nanotubes on the surface are more hydrophilic and also show worse biocompatibility properties for E. Coli bacteria.
