Characterization of tannic acid- and gallic acid-functionalized single- and multiwalled carbon nanotubes and an in vitro evaluation of their antioxidant properties

ABSTRACT

Objectives: Carbon nanotubes [CNTs] have powerful oxidative properties that influence their biomedical applications. This study addresses the oxidative potential of both single-walled carbon nanotubes [SWCNTs] and multiwalled carbon nanotubes [MWCNTs] by functionalizing them with tannic acid [TA] and gallic acid [GA], and an in vitro evaluation of their antioxidant properties is presented. Their effective role as antioxidants is influenced by their dual functions of reducing toxicity and inducing antioxidant effects
