Long-range charge transport in single G-quadruplex DNA molecules
(2014)DNA and DNA-based polymers are of interest in molecular electronics because of their versatile and programmable structures. However, transport measurements have produced a range of seemingly contradictory results due to ...

Numerical modelling for atomic-force-microscopy-based impedance imaging
(2005)This paper is motivated by the pioneering work of O'Hayre et al. and of Kalinin and Bonnell who brought together the imaging modalities of atomic force microscopy (AFM) and electrical impedance spectroscopy. With the ...

Physical constraints on charge transport through bacterial nanowires
(2012)Extracellular appendages of the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 were recently shown to sustain currents of 10 10 electrons per second over distances of 0.5 microns [El-Naggar et al., Proc. ...

Remodeling components of the tumor microenvironment to enhance cancer therapy
(2015)Solid tumor pathophysiology is characterized by an abnormal microenvironment that guides tumor progression and poses barriers to the efficacy of cancer therapies. Most common among tumor types are abnormalities in the ...

Self-assembly of an aspartate-rich sequence from the adenovirus fiber shaft: Insights from molecular dynamics simulations and experiments
(2014)The self-assembly of short peptides into fibrous nanostructures (such as fibrils and tubes) has recently become the subject of intense theoretical and experimental scrutiny, as such assemblies are promising candidates for ...

Supramolecular structures in nanocomposite multilayered films
(2006)We investigate the multilayered structures of poly(ethylene)oxide/ montmorillonite nanocomposite films made from solution. The shear orientation of a polymer-clay network in solution combined with simultaneous solvent ...

Vasodilator-Stimulated Phosphoprotein (VASP) depletion from breast cancer MDA-MB-231 cells inhibits tumor spheroid invasion through downregulation of Migfilin, β-catenin and urokinase-plasminogen activator (uPA)
(2017)A hallmark of cancer cells is their ability to invade surrounding tissues and form metastases. Cell-extracellular matrix (ECM)-adhesion proteins are crucial in metastasis, connecting tumor ECM with actin cytoskeleton thus ...
