Journal ArticleDOI
The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.
Journal ArticleDOI
Interaction of Silver(I) Ions with the Respiratory Chain of Escherichia coli: An Electrochemical and Scanning Electrochemical Microscopy Study of the Antimicrobial Mechanism of Micromolar Ag+†
Katherine B. Holt,Allen J. Bard +1 more
TL;DR: Electrochemical techniques were used to study the behavior of Escherichia coli on the addition of
Journal ArticleDOI
Bio-inspired CO2 Conversion by Iron Sulfide Catalysts Under Sustainable Conditions
Alberto Roldan,Nathan Hollingsworth,Anna Roffey,Husn-Ubayda Islam,Husn-Ubayda Islam,Josephine B. M. Goodall,C. R. A. Catlow,Jawwad A. Darr,Wim Bras,Gopinathan Sankar,Katherine B. Holt,Graeme Hogarth,N. H. de Leeuw +12 more
TL;DR: It is shown that particles of greigite can reduce CO2 under ambient conditions into chemicals such as methanol, formic, acetic and pyruvic acid and lend support to the Origin of Life theory on alkaline hydrothermal vents.
Journal ArticleDOI
Diamond at the nanoscale: applications of diamond nanoparticles from cellular biomarkers to quantum computing
TL;DR: In this paper, the authors present the wide-ranging applications of nanodiamond particles to date and discuss future research directions in this field, predicting a huge increase in research with these materials in the very near future.
Journal ArticleDOI
Scanning Electrochemical Microscopy and Conductive Probe Atomic Force Microscopy Studies of Hydrogen-Terminated Boron-Doped Diamond Electrodes with Different Doping Levels
TL;DR: In this paper, the pattern of conductivity and electrochemical activity at the surfaces of hydrogen-terminated boron-doped diamond electrodes, with different levels of doping, were measured using conductive probe atomic force microscopy and scanning electrochemical microscopy (SECM).
