Journal ArticleDOI
One-step green synthesis of gold and silver nanoparticles with ascorbic acid and their versatile surface post-functionalization
Ludivine Malassis,Remi Dreyfus,Ryan J. Murphy,Lawrence A. Hough,Bertrand Donnio,Bertrand Donnio,Christopher B. Murray +6 more
TL;DR: In this paper, the authors present a rapid and efficient synthesis of metallic gold and silver nanoparticles using ascorbic acid (vitamin C), which acts both as reducing and stabilizing agent.
Journal ArticleDOI
Threading synthetic polyelectrolytes through protein pores
TL;DR: This demonstration of threading a synthetic polyelectrolyte through a protein pore opens up many opportunities to systematically explore the fundamental physical principles behind translocation of single macromolecules, by resorting to the wide variety of synthetically available polymers without the complexities arising from the sequences of biological polymers.
Journal Article
Threading Synthetic Polyelectrolytes through Protein Pores
TL;DR: In this paper, the ionic current signatures of polystyrene sulfonate (polystyrene) are measured as its single molecules translocate through an alpha-hemolysin pore embedded into a bilayer in a salty aqueous medium under an externally applied electric field.
Journal ArticleDOI
Quantifying “Softness” of Organic Coatings on Gold Nanoparticles Using Correlated Small-Angle X-ray and Neutron Scattering
Benjamin T. Diroll,Kathleen M. Weigandt,Davit Jishkariani,Matteo Cargnello,Ryan J. Murphy,Lawrence A. Hough,Christopher B. Murray,Bertrand Donnio,Bertrand Donnio +8 more
TL;DR: A comparison between solid-state diffraction from self-assembled lattices of nanoparticles and the solution data from neutron scattering suggests that engineering softness/deformability in nanoparticle coatings is less straightforward than simply increasing the organic size.
Journal ArticleDOI
Scattering Studies on Poly(3,4-ethylenedioxythiophene)-Polystyrenesulfonate in the Presence of Ionic Liquids
Ryan J. Murphy,Kathleen M. Weigandt,David Uhrig,Ahmed Alsayed,Chantal Badre,Larry Hough,Murugappan Muthukumar +6 more
TL;DR: In this article, the authors investigated the nature of the interaction between PEDOT:PSS and 1-ethyl-3-methylimidazolium tetracyanoborate (EMIM:TCB) in solution state.
