Long Range Energy Transfer in Self-Assembled Stacks of Semiconducting Nanoplatelets

Long-range energy transfer in self-assembled quantum dot-DNA cascades.

The size-dependent energy bandgaps of semiconductor nanocrystals or quantum dots (QDs) can be utilized in converting broadband incident radiation efficiently into electric current by cascade energy transfer (ET) between layers of different sized quantum dots, followed by charge dissociation and transport in the bottom layer. Self-assembling such cascade structures with angstrom-scale spatial pr...

Energy transfer in self-assembled dipeptide hydrogels.

Energy transfer between a naphthalene-dipeptide and either a hosted dansyl acceptor or a co-assembling anthracene-dipeptide acceptor occurs on formation of a hydrogel by decreasing the pH.

Long-range energy transfer in proteins.

Proteins are large and complex molecular machines. In order to perform their function, most of them need energy, e.g. either in the form of a photon, as in the case of the visual pigment rhodopsin, or through the breaking of a chemical bond, as in the presence of adenosine triphosphate (ATP). Such energy, in turn, has to be transmitted to specific locations, often several tens of A away from wh...

Long-range ordering of highly charged self-assembled nanofilaments.

Charged nanoscale filaments are well-known in natural systems such as filamentous viruses and the cellular cytoskeleton. The unique properties of these structures have inspired the design of self-assembled nanofibers for applications in regenerative medicine, drug delivery, and catalysis, among others. We report here on an amphiphile of completely different chemistry based on azobenzene and a q...
