Description:

A method for the photo-mediated phase transfer of inorganic nanocrystals, such as luminescent quantum dots, QDs, is provided. Irradiation, specifically UV excitation (λex<400 nm), promotes the in-situ ligand exchange of hydrophobic quantum dots with hydrophilic ligands and their facile transfer to polar solvents and buffer media. The technique enables transfer of quantum dots and other nanocrystal materials from hydrophobic to polar and hydrophilic solutions.
