Ultraviolet-visible (UV-vis) spectroscopy, photoluminescence (PL) spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM) confirm that the CdTe QDs are formed via an extracellular growth and subsequent endocytosis pathway and have size-tunable optical properties with fluorescence emission from 490 to 560 nm and a cubic zinc blende structure with good crystallinity. In particular, the CdTe QDs with uniform size (2-3.6 nm) are protein-capped, which makes them highly soluble in water, and in situ bio-imaging in yeast cells indicates that the biosynthesized QDs have good biocompatibility. This work provides an economic and environmentally friendly approach to synthesize highly fluorescent biocompatible CdTe QDs for bio-imaging and bio-labeling applications.
