Biological synthesis of semiconductor zinc sulfide nanoparticles by immobilized Rhodobacter sphaeroides.
A novel, clean biological transformation reaction by immobilized Rhodobacter sphaeroides has been developed for the synthesis of zinc sulfide (ZnS) nanoparticles with an average diameter of 8 nm. The nanoparticles were examined by X-ray diffraction, transmission electron microscopy, energy dispersive analyses of X-rays, UV-vis optical absorption and photoluminescence spectra. The average diameter of ZnS nanoparticles varied according to the culture time.
