Abstract:

In this talk, we discuss a new approach to efficient photocurrent generation by using amphiphilic fullerene C60 derivatives assembled in phospholipids. Compared to most previous photoconversion systems based on supramolecular fullerene complexes, our approach relies on noncovalent formation of lipid bilayer on electrode to achieve precise placement of fullerene and therefore, can be quickly implemented in aqueous media. The advantage of having everything in water is taken further to design a sequence-specific DNA biosensor.
