Label-free photoelectrochemical cytosensing via resonance energy transfer using gold nanoparticle-enhanced carbon dots.
نویسندگان
چکیده
A universal and label-free photoelectrochemical cytosensing strategy was designed based on resonance energy transfer (RET) between carbon dots and cysteamine capped gold nanoparticles. RET promoted photo-to-current conversion efficiency and enhanced detection sensitivity. This proposed photoelectrochemical cytosensing platform exhibited a good performance for the assay of tumor cells with overexpressed receptors on cells.

Amino-functionalized green fluorescent carbon dots as surface energy transfer biosensors for hyaluronidase.
Amino-functionalized fluorescent carbon dots have been prepared by hydrothermal treatment of glucosamine with excess pyrophosphate. The produced carbon dots showed stabilized green emission fluorescence at various excitation wavelengths and pH environments. Herein, we demonstrate the surface energy transfer between the amino-functionalized carbon dots and negatively charged hyaluronate stabiliz...
متن کاملSurface plasmon enhanced Förster resonance energy transfer between the CdTe quantum dots
Förster resonance energy transfer FRET between CdTe quantum dots QDs at nanoscale proximity to gold nanoparticle Au NP layers is investigated experimentally. We have observed the enhancement in the acceptor QDs’ photoluminescence lifetime intensities. The decrease in donor QDs’ exciton lifetime from 5.74 to 2.06 ns, accompanied by an increase in acceptor QDs’ exciton lifetime from 3.38 to 7.52 ...

In this paper, an electrochemiluminescence resonance energy transfer (ECL-RET) system from CdS quantum dot to Ru(bpy)(3)(2+) was developed for the first time. By the signal amplification of Ru(bpy)(3)(2+) and the specific antibody-cell surface interactions, this ECL-RET system could sensitively respond down to 12.5 SMMC-7721 cells per mL.

The distance dependence of localized surface plasmon (LSP) coupled Förster resonance energy transfer (FRET) is experimentally and theoretically investigated using a trilayer structure composed of separated monolayers of donor and acceptor quantum dots with an intermediate Au nanoparticle layer. The dependence of the energy transfer efficiency, rate, and characteristic distance, as well as the e...
متن کاملSurface plasmon enhanced energy transfer between gold nanorods and fluorophores: application to endocytosis study and RNA detection.
Previously we have demonstrated surface plasmon enhanced energy transfer between fluorophores and gold nanorods under two-photon excitation using fluorescence lifetime imaging microscopy (FLIM) in both solution and intracellular phases. These studies demonstrated that gold nanoparticle-dye energy transfer combinations are appealing, not only in Förster resonance energy transfer (FRET) imaging, ...
