Fluorescence dynamics of the biosynthesized CdSe quantum dots in Candida utilis

Abstract Organisms served as factories of bio-assembly of nanoparticles attracted a lot of attentions due to the safe, economic and environmental-benignity traits, especially the fabrication of the super fluorescence properties quantum dots (QDs). However, information about the developmental dynamic...
