Capping Agents [Colloidal Quantum Dot (QD) Research Reagents] — gathers organic ligands such as long-chain carboxylic acids, amines, thiols, and phosphines that coat the surface of colloidal quantum dot nanocrystals. These ligands control solubility, colloidal stability, and the surface properties of nanoscale semiconductor particles.
Capping agents are used in the synthesis and post-synthesis of quantum dots to stabilize nanoparticles in organic solvents as well as water-based systems through ligand exchange. Nanomaterials and optoelectronics researchers use them to regulate surface density, prevent aggregation, and modify the optical and electronic properties of quantum dots in applications such as displays, solar cells, and fluorescence-based imaging labeling. Ligand selection also affects the compatibility of quantum dots with specific polymer matrices or solvents.

Pay attention to the carbon chain length, the surface-binding head group (carboxylate, thiol, amine, or phosphine), and ligand purity, as these factors determine coating efficiency and colloid stability. The physical form (liquid or solid) and oxygen-free storage conditions should also be considered for air-sensitive ligands. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
