Nanohybrids Composed of Quantum Dots and Cytochrome P450 as Photocatalysts

Synthesis with light: CdS quantum dots (QDs) generate superoxide and hydroxyl radicals upon UV irradiation in aqueous solution. The radicals are used for activating P450BSβ enzymes attached at the QD surface, effecting the catalytic transformation of myristic acid into α‐ and β‐hydroxymyristic acid...

Zusammenfassung:Synthesis with light: CdS quantum dots (QDs) generate superoxide and hydroxyl radicals upon UV irradiation in aqueous solution. The radicals are used for activating P450BSβ enzymes attached at the QD surface, effecting the catalytic transformation of myristic acid into α‐ and β‐hydroxymyristic acid (see picture, R=(CH2)10CH3).
