Orientation-controlled single-molecule junctions.

The conductivity of a single aromatic ring, perpendicular to its plane, is determined using a new strategy under ambient conditions and at room temperature by a combination of molecular assembly, scanning tunneling microscopy (STM) imaging, and STM break junction (STM-BJ) techniques. The construction of such molecular junctions exploits the formation of highly ordered structures of flat-oriente...

An approach to three-dimensional structures of biomolecules by using single-molecule diffraction images.

We describe an approach to the high-resolution three-dimensional structural determination of macromolecules that utilizes ultrashort, intense x-ray pulses to record diffraction data in combination with direct phase retrieval by the oversampling technique. It is shown that a simulated molecular diffraction pattern at 2.5-A resolution accumulated from multiple copies of single rubisco biomolecule...

Three-dimensional defocused orientation sensing of single bimetallic core-shell gold nanorods as multifunctional optical probes.

Bimetallic core-shell gold nanorods (AuNRs) are promising multifunctional orientation probes that can be employed in biological and physical studies. This paper presents the optical properties of single AuNRs coated with palladium (Pd) and platinum (Pt) under scattering-based dark-field (DF) microscopy. Strong longitudinal plasmon damping was observed for the bimetallic AuNRs due to Pd and Pt m...

Three-dimensional bead position histograms reveal single-molecule nanomechanics.

We describe a method to investigate the structure and elasticity of macromolecules by a combination of single molecule experiments and kinematic modeling. With a photonic force microscope, we recorded spatial position histograms of a fluctuating microsphere tethered to full-length myosin-II. Assuming only that the molecule consists of concatenated rigid segments, a model derived from robot kine...

Single-molecule three-color FRET.

Fluorescence resonance energy transfer (FRET) measured at the single-molecule level can reveal conformational changes of biomolecules and intermolecular interactions in physiologically relevant conditions. Thus far single-molecule FRET has been measured only between two fluorophores. However, for many complex systems, the ability to observe changes in more than one distance is desired and FRET ...
