Fig. 7From: Early signs of multi-walled carbon nanotbues degradation in macrophages, via an intracellular pH-dependent biological mechanism; importance of length and functionalizationRaman spectroscopy analysis of CNT recovered from cells cultured in presence or absence of Concanamycin. ID/IG ratio calculated from Raman spectra of S-, SF-, L-, or LF-CNT recovered from RAW 264.7 macrophages concomitantly exposed to CNT and Concanamycin A for 24 h (Panel a) or 48 h (Panel b). Abbreviations as in Fig. 1. Conca: Concanamycin A. Data are given as mean ± SEM of minimum 5 valuesBack to article page
