DNA imaged on a HOPG electrode surface by AFM with controlled potential.
Single-molecule AFM imaging of single-stranded and double-stranded DNA molecules self-assembled from solution onto a HOPG electrode surface is reported. The interaction of DNA with the hydrophobic surface induced DNA aggregation, overlapping, intra- and intermolecular interactions. Controlling the electrode potential and using the phase images as a control method, to confirm the correct topogra...
متن کاملAtomic force microscopy characterization of synthetic pyrimidinic oligodeoxynucleotides adsorbed onto an HOPG electrode under applied potential
In order to better understand the adsorption mechanism of nucleic acids at electrode surface, MAC Mode atomic force microscopy (MAC Mode AFM) was used to investigate the adsorption of a 10-base synthetic oligodeoxynucleotide (ODN) with the sequence 5′-CTTTTTCTTT-3′ containing o a T e a i i ©
متن کاملElectrode Potential Induced Reorientation of a Phospholipid Monolayer on a Mercury Electrode Surface
Rapid scan cyclic voltammetry has been employed to probe the potential induced transitions of a dioleoylphosphatidylcholine (diOPC) monolayer deposited onto a mercury surface. By employing two different types of electrodes, a hanging mercury drop electrode (HMDE) and a mercury-film-coated gold electrode (J-electrode), we were able to deposit the diOPC monolayer in tails-down and heads-down fash...
متن کاملExperimental investigations on a pre-chamber spark plug with variable heat range by integrating a controlled hot surface
In gasoline engines, pre-chamber spark ignition systems are used to achieve high efficiency and low NOx emissions when operating under lean conditions. While a cold pre-chamber spark plug can lead to misfiring and flame quenching under cold start or part load operation, a hot pre-chamber can result in uncontrolled pre-ignition phenomena under full load operation. This paper presents an approach...
متن کاملRestructuring of an Ir(210) electrode surface by potential cycling
This study addresses the electrochemical surface faceting and restructuring of Ir(210) single crystal electrodes. Cyclic voltammetry measurements and in situ scanning tunnelling microscopy are used to probe structural changes and variations in the electrochemical behaviour after potential cycling of Ir(210) in 0.1 M H2SO4. Faceted structures are obtained electrochemically as a function of time ...
