Quantitative Analysis of Ligand-Chelation Dynamics and Critical Grafting Density for the Long-Term Steric Isolation of Colloidal Upconversion Nanoparticles.
Transmission electron microscopy (TEM) is routinely used to validate the morphological uniformity of colloidal nanoparticles. These assessments fail to provide direct evidence of steric isolation of nanoparticles, often resulting in unforeseen failures during downstream engineering processes. This study quantitatively...
