Molecular Engineering of Acoustic Protein Nanostructures

Molecular engineering of photoresponsive three-dimensional DNA nanostructures.

This study demonstrates the use of azobenzene-incorporated DNA as a control agent to precisely monitor three-dimensional DNA nanostructures. The shape of a DNA tetrahedron can be controlled by alternate irradiations with different wavelengths of light.

Simulated engineering of nanostructures

Results are reported from two molecular-dynamics simulations designed to yield insight into the engineering of nanometre-scale structures. The first is the initial stages of the indentation of a silicon substrate by an atomically-sharp diamond tip. Up to an indentation depth of approximately 0.6 nm the substrate responds elastically and the profile of the disturbed region of the substrate norma...

Acoustic solitons in semiconductor nanostructures

The present lecture gives the review of recent studies where acoustic solitons strongly influence the electron states in a semiconductor nanostructure. The amplitude of soliton pulses is so high that the electron states in a quantum well make temporal excursions in energy up to 10 meV. The subpicosecond duration of the solitons is less than the coherence time of the optical transition between t...

Protein engineering for molecular electronics.

Recombinant DNA technology allows the manipulation of the physical properties of proteins that perform electron transport and photochemical processes. Recent work is reviewed that has a potential impact on the development of molecular electronic devices, within a general framework outlining strategies for device fabrication. This review is also published in Current Opinion in Structural Biology...
