- •
Fission yeast and hairy roots of tomato were compared as in vitro production systems for biological synthesis of CdS quantum dots.
- •
The rate of production and yield of CdS nanoparticles was lower in the hairy root cultures compared with yeast.
- •
Yeast-produced CdS nanocrystallites were smaller than those produced by hairy roots.
- •
Hairy roots produced quantum dots of higher fluorescence quantum efficiency and greater photostability than those generated by yeast.
- •
Choice of cellular host had a significant effect on the yield, production rate and functional properties of biologically produced quantum dots.
