Photoenzymatic synthesis through sustainable NADH regeneration by SiO2-supported quantum dots.

Sustainable photochemical NADH regeneration and redox-enzymatic synthesis are accomplished by using CdS nanocrystals grown on the surface of SiO(2) beads. CdS nanocrystals grown on SiO(2) beads worked efficiently as a visible-light absorbing photocatalyst for in situ NADH regeneration with high catalytic activity and minimal loss of activity despite repeated uses.
