Silver nanoparticles exhibit antibacterial properties via bacterial inactivation and growth inhibition. The mechanism is not yet completely understood. This work was aimed at elucidating the effect… (More)
Silver nanocrystals grown on a poly(dG)-poly(dC) double stranded DNA scaffold displayed circular dichroism at their surface plasmon excitation band. This chiral plasmon signature was not observed in… (More)
The preparation of conductive and transparent gold/silver nanowire mesh films is reported. The nanowires formed after the reduction of the metal ions was triggered and a thin growth solution film was… (More)
The excitation of surface plasmons at rough noble-metal surfaces is responsible for the enhancement of several optical phenomena observed for molecules adjacent to these surfaces, such as… (More)
Chirality is a key aspect in the evolution of life and plays an important role in structure–function relationships and recognition in biological systems. Interest in this property extends from… (More)
Control of biofouling and its negative effects on process performance of water systems is a serious operational challenge in all of the water sectors. Molecularly capped silver nanoparticles… (More)
We report on in situ, self-assembly, solution-processing of metallic (Au/Ag) nanowire-based transparent electrodes integrated to vertical organic field-effect transistors (VOFETs). In the VOFET… (More)
High-temperature hydrolysis of Zn(II) and Mn(II) alkoxides in a high boiling point solvent in the presence of surfactants was used to prepare surfactant-coated Zn(1-x)Mn(x)O nanocrystals with average… (More)
At the Advanced Photon Source (APS) at Argonne National Laboratory (ANL), a fke-electron laser (FEL) based on the self-amplified spontaneous emission (SASE) process is nearing completion. Recently,… (More)
