Silver Nanoparticles Substantially Enhance Fluorescence of Chlorophyll

Formation of Silver Nanoparticles Using Fluorescence Properties of Chitosan Oligomers

In this study, silver chloride nanoparticles (AgCl NPs) were prepared using chitosan oligomer (CHI) and chitosan oligomer derivatives (CHI-FITC). The CHI and CHI-FITC were used as markers to confirm the formation of AgCl NPs using their fluorescence properties as well as stabilizers. The fluorescence properties of CHI and CHI-FITC were monitored by a luminescence spectrophotometer, and the morp...

Computational study of fluorescence scattering by silver nanoparticles.

We study the nature of fluorescence scattering by a radiating fluorophore placed near a metal nanoparticle with the finite-difference time-domain method. Angle-resolved light-scattering distributions are contrasted with those that result when ordinary plane waves are scattered by the nanoparticle. For certain sized nanoparticles and fluorophore dipoles oriented parallel to the metal surface, we...

Effect of Nanoparticles and Biofertilizers on Chlorophyll Fluorescence Indices and Some Physiological Traits of Triticale (Triticosecale Wittmack) under Salinity Stress

In order to study the effects of nanoparticles and biofertilizers on chlorophyll fluorescence indices and some physiological traits of triticale (Triticosecale Wittmack) under salinity stress, a factorial experiment was conducted based on a randomized complete block design with three replications in the research greenhouse of Faculty of Agriculture and Natural Resources, University of Mohaghegh...

Near-Infrared Surface-Enhanced Fluorescence Using Silver Nanoparticles in Solution

Silver nanoprism enhanced fluorescence in YVO4:Eu3+ nanoparticles.

Silver nanoprisms of different sizes influence fluorescence enhancement in YVO4:Eu(3+) nanoparticles to various degrees under excitation of green light (532 nm). The local field generated by silver nanoprisms and their dimers is simulated through the FDTD method and a direct correlation with fluorescence enhancement is established.
