Directional electroswitchable photocurrents in the CdS nanoparticle/dsDNA/intercalator
system.
a
Enhanced generation of an anodic photocurrent in the presence of the doxorubicin inter-
calator (3; applied potential
E
=
0 V).
b
Enhanced generation of a cathodic photocurrent in the
presence of the reduced methylene blue intercalator (4a; applied potential
E
=
0.4 V).
c
Enhanced
generation of an anodic photocurrent in the presence of the oxidized methylene blue intercalator
(4b; applied potential
E
=
0 V). The redox levels of the components that participate in the differ-
ent photocurrent-generating systems are presented on the right side of the scheme.
