Mimikry eines Lichtsammelkomplexes zur Beschleunigung der Photooxidation in asymmetrischen Lipidmembran‐Nanoreaktoren

open access: yesAngewandte Chemie, EarlyView.
Biomimetische Liposomen‐Nanoreaktoren, die natürliche Lichtsammelkomplexe nachahmen, ermöglichen eine effiziente Photooxidation von NADH. Membrangebundenes Fluorescein überträgt Energie über FRET an membrangebundenes Eosin Y und oxidiert so NADH.
