Abstract In this work, we synthesized water soluble and biocompatible ultrasmall Gd2O3 nanoparticles coated with various ligands were investigated. These ligands include small diacids with hydrophobic chains, namely, succinic acid, glutaric acid, and terephthalic acid, and large polyethylenimines (PEIs) with hydrophilic chains, namely, PEI-1300 and PEI-10000. Ligand-size and ligand-chain hydrophilicity effects were observed. The r1 and r2 values generally decrease with increasing ligand-size.The structural, morphological, surface coating, toxicity and their application are studied.
