Single-Molecule Orthogonal Double-Click Chemistry—Inorganic to Organic Nanostructure Transition

Single-molecule devices as scaffolding for multicomponent nanostructure assembly.

We report here a method to integrate discrete multicomponent assembly into molecular electronic devices. We first functionalize a molecule wired between the ends of a single-walled carbon nanotube so that it can be derivatized with a probe molecule. This probe then binds to a complementary biomolecule to form a noncovalent complex. Each step of chemical functionalization and biological assembly...

Equilibrium and transition between single- and double-headed binding of kinesin as revealed by single-molecule mechanics.

Kinesin is a processive motor protein that "walks" on a microtubule toward its plus end. We reported previously that the distribution of unbinding force and elastic modulus for a single kinesin-microtubule complex was either unimodal or bimodal depending on the nucleotide states of the kinesin heads, hence showing that the kinesin may bind the microtubule either with one head or with both heads...

Single Chain Core-Shell Nanostructure

A combination of static and dynamic laser light scattering has revealed that at temperatures higher than ,33 ±C a linear poly(N-isopropylacrylamide) chain grafted with poly(ethylene oxide) (PNIPAMg-PEO) in water can undergo a “coil-to-globule” transition to form a stable single chain core-shell nanostructure with the collapsed PNIPAM chain backbone as the hydrophobic core and the grafted PEO br...
