Fig. 7From: Biosynthesis, characterization of PLGA coated folate-mediated multiple drug loaded copper oxide (CuO) nanoparticles and it’s cytotoxicity on nasopharyngeal cancer cell linesLive dead assay of CNE-2 cells on treatment with (a) PBS; b CuO NPs; c FOL-PLGA-CuO NPs; d CD-1; e CD-2; f CD-3. Note the reduced cell size and huge number of dead cells in (b) indicating potent cytotoxic effects much reduced in other formulationsBack to article page
