Gold nanorods-based FRET assay for ultrasensitive detection of Hg2+.
نویسندگان
چکیده
A fluorescence method for detecting mercury ion in a homogeneous medium is proposed with gold nanorods (GNRs) as a fluorescence quencher on the basis of the fluorescence resonance energy transfer (FRET). Under the optimum conditions, the method exhibits a dynamic response range from 10 pM to 5 nM with a detection limit of 2.4 pM.

Gold nanorods-based FRET assay for ultrasensitive detection of DNA methylation and DNA methyltransferase activity.
A fluorescence method for the detection of DNA methylation and the assay of methyltransferase activity is proposed using gold nanorods as a fluorescence quencher on the basis of fluorescence resonance energy transfer. It is demonstrated that this method is capable of detecting methyltransferase with a detection limit of 0.25 U mL(-1), which might make this method a good candidate for monitoring...
متن کاملGold nanorods-based FRET assay for sensitive detection of Pb2+ using 8-17DNAzyme.
In this paper, we have reported a sensitive assay for fluorescence "turn-on" detection of Pb(2+) in aqueous solutions based on FRET between gold nanorods (GNRs) and the FAM-labeled substrate strand of 8-17DNAzyme. The fluorescence of the FAM-labeled substrate strand is quenched when 8-17DNAzyme is adsorbed on GNRs surface through electrostatic interaction. In the presence of lead ions, the fluo...
متن کاملAn ultrasensitive, non-enzymatic glucose assay via gold nanorod-assisted generation of silver nanoparticles.
This report demonstrates a colorimetric, non-enzymatic glucose assay with a low detection limit of 0.07 μM based on negatively charged gold nanorod-enhanced redox reaction. This glucose assay could generate silver nanoparticles as the readout that can be visualized by the naked eye, and only 4 femtomoles of nanorods are needed for glucose determination in one human plasma sample.
متن کاملAttomolar detection of protein biomarkers using biofunctionalized gold nanorods with surface plasmon resonance.
This paper describes an ultrasensitive surface plasmon resonance (SPR) detection method using biofunctionalized gold nanorods for the direct detection of protein biomarkers. Immunoglobulin E (IgE), which has separate antibody and DNA aptamer binding sites, was chosen as a model protein for which a sandwich assay platform was designed. Detection was achieved via the specific adsorption of unlabe...
