Fig. 6From: Theoretical study of interaction between temozolomide anticancer drug and hydroxyethyl carboxymethyl cellulose nanocarriers for targeted drug delivery by DFT quantum mechanical calculationGenerated molecular electrostatic potential (MEP) maps of temozolamide drug (a) and temozolamide-nanocellulose complex (b). The negative (red, orange, and yellow) regions are related to electrophilic reactivity, whereas positive (green and blue) regions accompany nucleophilic reactivityBack to article page
