Identification of Chinese Herbs Using a Sequencing-Free Nanostructured Electrochemical DNA Biosensor
Due to the nearly identical phenotypes and chemical constituents, it is often very challenging to accurately differentiate diverse species of a Chinese herbal genus. Although technologies including DNA barcoding have been introduced to help address this problem, they are generally time-consuming and require expensive sequencing. Herein, we present a simple sequencing-free electrochemical biosen...
متن کاملDesign of DNA nanostructure-based interfacial probes for the electrochemical detection of nucleic acids directly in whole blood† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c7sc04663d
Here we report a robust and sensitive DNA nanostructure-based electrochemical (E-nanoDNA) sensor that utilizes tetrahedral DNA nanostructures (TDNs) as an interfacial probe to detect biomolecules in a singlestep procedure. In this study, we have firstly demonstrated that the use of TDNs can significantly suppress electrochemical background signals compared to traditional linear DNA probes upon ...
متن کاملFacile Synthesis and Electrochemical Performance of Graphene-Modified Cu2O Nanocomposite for Use in Enzyme-Free Glucose Biosensor
Graphene-modified Cu2O nanocomposite was synthesized under facile microwave irradiation of an aqueous solution and has been investigated as an enzyme-free glucose biosensor. Morphology and crystal structure of the graphene-modified Cu2O nanocomposite were investigated by using electron microscopy and X-Ray Diffraction (XRD) analyses. Also, the electrochemical performan...
متن کاملA Label-free Electrochemical Biosensor for Acrylamide Based on DNA Immobilized on Graphene Oxide-Modified Glassy Carbon Electrode
Acrylamide (AA) is a widely used chemical compound, which has strong neurotoxicity, and potential carcinogenicity and genotoxicity. In the present work, the interaction between AA and DNA was confirmed by UV-visible spectroscopy. According to such an interaction, a label-free DNA biosensor for electrochemical determination of AA was proposed. To fabricate the sensor, graphene oxide (GO) was fir...
متن کاملRapid and sensitive electrochemical detection of DNA with Silver nanoparticle dispersed poly (9, 9-dioctylfluorene-ran-phenylene) nanocomposites
In this study a sensitive electrochemical sensor for the detection of E.coli has been developed using silver nanoparticle (Ag) embedded poly(9,9-dioctylfluorene-ran-phenylene) (CFP) nanocomposite as a conductive platform and DNA hybridization technique. The new polymer was synthesized from 9,9-dioctylfluorene and 1,3-dichlorobenzene and biphenyl through Friedel Crafts alkylation reacti...
