The LOTUS project builds carbon nanotube-based sensors to measure the level of different chemicals in water. In the framework of its research on the sensors, Bérengère Lebental from the University Gustave Eiffel conducted a study on the tip-enhanced raman spectroscopy of polymer functionalised multiwalled carbon nanotubes.

“In this work, after comparing the Tip-enhanced Raman spectroscopy (TERS) performand of commercial Ag coated nanotips and home-made bulk Au tips on bare Multiwalled carbon nanotubes (MWCNTs), we show how TERS can be exploited for characterizing MWCNTs mixed with conjugated fluorene copolymers, thus contributing to the understanding of the polymer/CNT interaction process at the local scale.”
