چکیده
A DNA-Au NP probe for sensing Hg2+ using the formation of DNA-Hg2+ complexes through thymidine (T)-Hg2+ -T coordination to control the negative charge density of the DNA strands-thereby varying their structures-adsorbed onto Au NPs.

Determination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles
Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...
متن کاملRadial Flow Assay Using Gold Nanoparticles and Rolling Circle Amplification to Detect Mercuric Ions
A novel colorimetric assay employing oligonucleotide-conjugated gold nanoparticle (AuNP probes) and rolling circle amplification (RCA) was developed for simple detection of mercuric ions (Hg2+). The thymine-Hg2+-thymine (T-Hg2+-T) coordination chemistry makes our detection system selective for Hg2+. In the presence of Hg2+, the thymine 12-mer oligonucleotide is unable to act as a primer for RCA...
متن کاملA Portable Smart-Phone Readout Device for the Detection of Mercury Contamination Based on an Aptamer-Assay Nanosensor
The detection of environmental mercury (Hg) contamination requires complex and expensive instruments and professional technicians. We present a simple, sensitive, and portable Hg2+ detection system based on a smartphone and colorimetric aptamer nanosensor. A smartphone equipped with a light meter app was used to detect, record, and process signals from a smartphone-based microwell reader (MR S-...
متن کاملConstruction of a Carbon Paste Electrode Based on Novel Thiolated Ligand Capped Gold Nanoparticles for Determination of Trace Amounts of Mercury(II)
In the present study, a simple electrochemical sensor for trace determination of Hg(II) ions in aqueous solutions was introduced. The proposed sensor was designed by incorporation of the 4-methyl-piperidine-carbodithioate capped gold nanoparticles (GNPs) into the carbon paste electrode (CPE), which provides a remarkably improved sensitivity for stripping voltammetric determination of Hg(II). Di...
متن کاملHighly Selective and Ultrasensitive Turn-On Luminescence Chemosensor for Mercury (II) Determination Based on the Rhodamine 6G Derivative FC1 and Au Nanoparticles
A method for the detection and quantitation of Hg2+ in aqueous samples by fluorescence spectroscopy is presented. It consists of a turn-on sensor developed by coupling Gold nanoparticles (AuNPs) with the rhodamine 6G derivative FC1, in which the response is generated by a mercury-induced ring-opening reaction. The AuNPs were included in order to improve the sensitivity of the method towards the...
