Bioconjugation between CdTe nanowires and Au nanoparticles: Fluorescence enhancement
نویسندگان
چکیده
The interaction between semiconductor nanowires (NWs) and metallic nanocolloids were studied upon bioconjugation of two biomaterials: d-biotin and streptavidin. 5-fold intensity enhancement of luminescence and a blue shift of the emission peak were observed after conjugation with Au NPs. It can be interpreted in terms of the electromagnetic field enhancement effect in the presence of metallic NPs and demonstrated that the strong luminescence enhancement should be treated as a collective response of Au-NPs.

Nanoparticle/nanowire assemblies with a degree of radial organization were prepared around luminescent semiconducting CdTe nanowires using bioconjugation with streptavidin and D-biotin linkers. Red-emitting nanowires (6.62 +/- 1.55 nm diameter, 512 +/- 119 nm length) and green-emitting nanoparticles (3.2 +/- 0.7 nm diameter) were surface-modified with biotin, while orange-emitting nanoparticles...
متن کاملControllable photoluminescence enhancement of CdTe/CdS quantum dots thin films incorporation with Au nanoparticles
Au nanoparticles (Au NPs)/CdTe/CdS QDs nanocomposite films were fabricated by deposition of Au NPs and layer-by-layer self-assembly of colloidal CdTe/CdS QDs. Photoluminescence (PL) spectra showed that Au NPs incorporation resulted in an increase of PL intensity about 16-fold compared with that of the samples without Au NPs. PL enhancement of Au NPs/CdTe/CdS QDs nanocomposite films can be contr...

متن کاملSurface modification, functionalization and bioconjugation of colloidal inorganic nanoparticles.
Inorganic colloidal nanoparticles are very small, nanoscale objects with inorganic cores that are dispersed in a solvent. Depending on the material they consist of, nanoparticles can possess a number of different properties such as high electron density and strong optical absorption (e.g. metal particles, in particular Au), photoluminescence in the form of fluorescence (semiconductor quantum do...
متن کاملInteraction of surface plasmons with CdTe quantum dot excitons
A 5-fold enhancement in the luminescence of CdTe nanocrystal quantum dots (QDs) is observed when they are placed in proximity to a nanostructured Au film deposited by pulsed laser deposition technique. No enhancement is observed with a nanostructured Ag film. The enhancement is due to the interaction of the QDs excitons with the localized surface plasmons (LSP). The Au surface plasmon (SP) freq...
