Fig. 3From: Carboxylated graphene quantum dots-mediated photothermal therapy enhances drug-membrane permeability, ROS production, and the immune system recruitment on 3D glioblastoma modelsCombined effect of GQDs and chemotherapy on spheroid models of glioblastoma. A Bright field images of spheroids at 0, 7, and 14 days from administration of GQDs. B Growth of spheroids treated with GQDs and DOX. C Cell viability of spheroids treated with GQDs and DOX at 7 and 14 days from administration of GQDs. D Growth of spheroids treated with GQDs and temozolomide (TMZ). E Cell viability of spheroids treated with GQDs and TMZ at 7 and 14 days from administration of GQDs. ***p < 0.01 one-way ANOVA and Tukey post-hoc testBack to article page
