Non-Invasive Probing of Nanoparticle Electrostatics

Dr. Kristina Tschulik, Dr. Wei Cheng, Dr. Christopher Batchelor-McAuley, Stuart Murphy, Dr. Dario Omanović and Prof. Dr. Richard G. Compton

Non-Invasive Probing of Nanoparticle ElectrostaticsNot what you might think: A new and non-invasive technique to probe the electrostatic interaction between surface-charged nanoparticles and a charged metal/solution interface shows that electrostatic effects are insignificant in all but very dilute electrolytes.

Impact of the Counter-Electrode Material on Redox Processes in Resistive Switching Memories

Stefan Tappertzhofen, Prof. Dr. Rainer Waser and Dr. Ilia Valov

Impact of the Counter-Electrode Material on Redox Processes in Resistive Switching MemoriesRole of Counter Charges: The impact of various counter-electrode (CE) materials on the redox processes prior to resistive switching is investigated. The different catalytic activities of CEs towards the water redox process determines the defect concentration within resistively switching oxides.

EarlyViewManipulation of Single-Stranded DNA Using an Artificial Site-Selective DNA Cutter composed of Cerium(IV)/EDTA and Phosphonate–Oligonucleotide Conjugates

Yuichiro Aiba, Tuomas Lönnberg, and Makoto Komiyama*

An artificial DNA cutter with high site-specificity, was successfully developed by the combination of cerium(IV)/EDTA and two ethylenediamine-N,N,N’,N’-tetrakis(methylenephosphonic acid)-oligonucleotide conjugates. By using this DNA cutter, the sense strand of blue fluorescent protein (BFP) gene was selectively cut at a predetermined site in the chromophore-coding region. The upstream fragment obtained by the site-selective scission was ligated with a downstream fragment of the closely related green fluorescent protein (GFP) gene. The recombinant gene was successfully expressed in E. coli and the chimeric chromophore emitted green fluorescence as expected.
