Fabrication of Upconverting Hybrid Nanoparticles for Near-Infrared Light Triggered Drug Release
Figure 3
High-resolution TEM micrographs of the self-assemblies of (a) p1 and (b) p2. Insets are corresponding hydrodynamic diameter distributions recorded by DLS. Note. Staining was performed with phosphotungstic acid and the tiny particles may be the crystal of excess phosphotungstic acid.
