Abstract:

Staphylococcus aureus cells were skillfully utilized to produce ZnSe quantum dots and transformed into fluorescing cells through temporally-spatially coupling strategy. The products were characterized by means of transmission electron microscopy(TEM), atomic force microscope(AFM), dynamic light scattering(DLS), inductively coupled plasma emission spectrometry(ICP-AES), UV-Vis absorption spectroscopy and photoluminescence(PL) spectroscopy. ZnSe QDs biosythesized by such a method possess uniform particle size of (2.96±0.76) nm and good dispersibility with fluorescence emission at 537 nm.

Key words: ZnSe, Quantum dots, Staphylococcus aureus, Live-cell, Biosynthesis
