Scientists from Tsinghua University in China have found a way to synthesis water soluble nanocrystals with sizes smaller than 10nm using a formamide solvent-system.
So far, many groups have been successful in synthesising hydrophobic nanocrystals, but their inability to disperse in water has hindered their applications in electronics, catalysis and biomedicine. Hydrophobic nanocrystals can be made hydrophilic by using ligands to modify the surface, although these post-synthesis treatments are usually time-consuming and not environmentally friendly. Wang and co-workers have solved these problems with their direct synthesis of water-soluble nanocrystals, which does not use toxic solvents and has no need for post-modifications.
