Enhanced fluorescence images for labeled cells on silver island films. [PDF]
Langmuir, 2008 Silver island films (SIFs) were deposited on the glass substrates to serve as the supports. T-lymphocytic (PM1) cell lines were labeled by Alexa Fluor 680 dextran conjugates on the membranes or by YOYO in the nucleus, respectively.

Decreasing photobleaching by silver island films: application to muscle. [PDF]
Anal Biochem, 2007 Recently it has become possible to study interactions between proteins at the level of single molecules. This requires collecting data from an extremely small volume, small enough to contain one molecule-typically of the order of attoliters (10(-18) L).

Plasmon-enhanced sensitization of singlet oxygen on silver island films
Қарағанды университетінің хабаршысы. Физика сериясыThe influence of the plasmonic effect of silver island films on the absorption, fluorescence and long-term luminescence of rose bengal in polyvinyl butyral films has been studied. Under the plasmon effect, the optical density of the dye increased by 3.3

Single-Molecule Studies of Enhanced Fluorescence on Silver Island Films [PDF]
Plasmonics, 2007 We investigated enhanced fluorescence of Cyanine 5 dyesnear silver island films (SIFs) by the use of single moleculespectroscopic method. We found that, on average, the Cy5molecules are 18-fold brighter on SIFs than on a glasssurface and that single-molecule lifetimes are 10-foldshorter on SIFs as compared to glass.

Enhancement of enzymatic colorimetric response by silver island films on high throughput screening microplates. [PDF]
J Immunol Methods, 2014 In this study, we report the use of an enzyme-based hybrid platform, which is comprised of silver island films, enzymes (HRP and AP) and high-throughput screening (HTS) microplates, to enhance the colorimetric response of enzymatic reactions.

Out-diffused silver island films for surface-enhanced Raman scattering protected with TiO2 films using atomic layer deposition. [PDF]
Nanoscale Res Lett, 2014 We fabricated self-assembled silver nanoisland films using a recently developed technique based on out-diffusion of silver from an ion-exchanged glass substrate in reducing atmosphere.

Angular-Dependent Metal-Enhanced Fluorescence from Silver Island Films. [PDF]
Chemical Physics Letters, 2008 In this Letter we report the observation of angular-dependent metal-enhanced fluorescence (MEF) from fluorophores deposited onto silver island films (SiFs). When illuminated with laser light (473nm) at angles of 45° and 90° from the surface, SiFs scattered light at wide observation angles biased by the direction of the incident light.
