Nano-Galaxy: GQDs and Iron Oxide in Tumor Scaffold
This confocal-style composite image captures the hybrid integration of fluorescent graphene quantum dots (GQDs, green) and magnetic iron oxide nanoparticles (Fe₃O₄, red) within a biomimetic hydrogel scaffold. Designed for a 3D in vitro tumor model, the structure mimics the extracellular matrix while enabling photothermal therapy and magnetic guidance. The distribution highlights nanoparticle retention and spatial arrangement within the porous hydrogel, emphasizing its potential for localized cancer treatment and real-time imaging. The artificial coloring enhances the visual appeal without altering the original signal. Note: Image represents preliminary findings. Data not published. Instrument used to produce the image: Confocal Laser Scanning Microscope (CLSM)
