Papers
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.

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.

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.

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.
Deformation and retentive force following in vitro cyclic fatigue of cobalt-chrome and aryl ketone polymer (AKP) clasps
Ali Marie,Andrew Keeling,T. Paul Hyde,Brian Nattress,Sue Pavitt,Ryan J. Murphy,Timothy James Shary,Sean Dillon,Cecilie Osnes,David Wood +9 more
TL;DR: The retentive force for the Ultaire™ AKP clasps was consistent over 15,000 cycles of fatigue mimicking prolonged clinical use; the AKP material was more robust; showing minimal deformation even in non-ideal paths of removal, as many patients would routinely use.
