Spectrally selective fluorescence imaging of Chlorobaculum tepidum reaction centers conjugated to chelator-modified silver nanowires [PDF]

, 2017
A polyhistidine tag (His-tag) present on Chlorobaculum tepidum reaction centers (RCs) was used to immobilize photosynthetic complexes on a silver nanowire (AgNW) modified with nickel-chelating nitrilo-triacetic acid (Ni-NTA).

Immobilization of enzymes to silver island films for enhanced enzymatic activity [PDF]

Journal of Colloid and Interface Science, 2014
The performance of the enzyme-based biosensors depends on the enzymatic activity and the use of an appropriate technique for immobilization of enzymes. The incorporation of silver island films (SIFs) into the enzyme-based biosensors is expected to enhance the enzymatic activity and to increase the detectability of analytes of interest.Two enzymes, β ...

Revisiting semicontinuous silver films as surface-enhanced Raman spectroscopy substrates

Beilstein Journal of Nanotechnology, 2019
Surface-enhanced Raman spectroscopy (SERS) is a very promising analytical technique for the detection and identification of trace amounts of analytes. Among the many substrates used in SERS of great interest are nanostructures fabricated using physical ...

Giant third optical harmonic generation in island silver films

Journal of Experimental and Theoretical Physics Letters, 2004
Giant third optical harmonic (TH) generation has been experimentally observed in island silver films. The TH intensity in the island silver films studied is more than two orders of magnitude higher than the value observed for the smooth surface of a homogeneous silver film. The mechanism of enhancement of the nonlinear cubic response is associated with

Surface-enhanced optical third-harmonic generation in Ag island films

, 2005
Surface-enhanced optical third-harmonic generation (THG) is observed in silver island films. The THG intensity from Ag nanoparticles is enhanced by more than two orders of magnitude with respect to the THG intensity from a smooth and homogeneous silver ...

In-situ evolution and aging of ultrathin sputter deposited silver films

Applied Surface Science Advances
Silver (Ag) thin films deposited by magnetron sputtering are widely utilized in optics, antimicrobial coatings, and flexible organic electronics. However, the inherent three-dimensional (3D) island growth of Ag complicates the fabrication of ultrathin ...

Submicrometre-thick optical polarising films for800 nm using stretched silver island films

Electronics Letters, 1997
An ultra-thin optical polarising film consisting of stretched metal island films has been investigated for commercially available 800 nm laser diodes. The authors have experimentally found that silver is the most useful choice of metal for 800 nm for island films, compared with other metals such as gold, copper, and aluminium.
