Growth, cellular morphology and fluorescence study of GNP theranostic nanocomposites at different time points. a The growth, cellular morphology and the fluorescence under different filters. Green colour shows the presence of nanoparticles, while red fluorescence is due to doxorubicin. Examination confirmed the prolonged drug presence with controlled drug release even at 72 h. b Intracellular tracking, receptor binding and intracellular localization of GNP theranostic nanomedicine that cause variation in binding and fluorescent intensities correlated to nanoparticles and doxorubicin concentration at 6, 12, 24, 48, and 72 h
