Thiamine hydrochloride-capped CdSe/polyethylene glycol nanospheres were synthesised via one-pot technique. The nanospheres were characterized by FTIR, XPS,TEM and fluorescence spectra. FTIR and XPS analysis confirmed the capping of the nanoparticles by the thiamine hydrochloride. TEM image displayed that the nanospheres were small and spherical in shape with good dispersion. The fluorescence spectra illustrated that the nanospheres exhibited emission at about 515nm. Optimum condition for synthesis is pH 11, 40 ℃ for 2h and n(Cd)/n(thiamine hydrochloride) = 1︰8.
