Fig. 6From: rGO nanomaterial-mediated cancer targeting and photothermal therapy in a microfluidic co-culture platformConfocal laser scanning microscopy images of cellular uptake after treatment with 30 μg/mL of rGO-PEG-FA nanomaterials in a microfluidic co-culture platform. Images of the HUVEC (a), Co-culture (b), and MDA-MB-231 (c) channel. High magnification images (d–f). White arrows indicate nanomaterial uptake in cells. Scale bars are 100 μmBack to article page
