Fig. 1From: CoFe2O4-Quantum Dots for Synergistic Photothermal/Photodynamic Therapy of Non-small-Cell Lung Cancer Via Triggering Apoptosis by Regulating PI3K/AKT PathwayPreparation and characterization of CoFe2O4-QDs. a The representative TEM image of as-prepared CoFe2O4-QDs. Scale bar, 20 nm. b A global analysis of the size of CoFe2O4-QDs with the average diameter 3.4 nm. The inset is the representative digital photo of the CoFe2O4-QDs suspension. c The lattice fringes of as-prepared nanocrystals correspond to CoFe2O4-QDs HRTEM image. Scale bar, 2 nm. d The as-prepared CoFe2O4-QDs exhibited uniform distribution of Co, Fe and O. The representative elements map was shownBack to article page
