Fig. 4From: In-vitro cytotoxicity assessment of carbon-nanodot-conjugated Fe-aminoclay (CD-FeAC) and its bio-imaging applications a Power X-ray diffraction (XRD) patterns and b Fourier transform infrared (FT-IR) spectra of i FeAC, ii CD, and iii CD-FeAC NPs in KBr-pellet mode. In b iii, the red dotted circles indicate amide bondings (C=O stretching, N–H deformation, and C–N stretching)Back to article page
