CNTs have attracted considerable interest not only for their outstanding physical properties, but also for their potential toxicological risks as nanoparticles (NP).The overall toxic response has proven problematic due to their interaction with colorimetric assay methods.In this work,in vitro cells were examined using Raman spectroscopy.It shows that it can be well differentiated on the basis of spectral features.The responses, the effect of oxidant production and medium depletion on the Raman spectral response and toxicology of the cell are examined independently.These...
