Electrochemical detection of single E. coli bacteria labeled with silver nanoparticles.

چکیده
A proof-of-concept for the electrochemical detection of single Escherichia coli bacteria decorated with silver nanoparticles is reported. Impacts of bacteria with an electrode - held at a suitably oxidizing potential - lead to an accompanying burst of current with each collision event. The frequency of impacts scales with the concentration of bacteria and the charge indicates the extent of decoration.

Electrochemical assay of anti-tetanus toxoid monoclonal antibody by silver enhancement of gold nanoparticles at carbon nanotubes modified glassy carbon electrode
Tetanus is caused by the toxin secreted by Clostridium tetani. Due to the rapid infection with this bacterium, it is so important to investigate the tetanus immunity of people. Therefore, electrochemical biosensors, as one of the most effective tools in this regard, have demanded characteristics such as being fast, simple, cost-effective and portable. However, their detection sensitivity is not...
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...

Silica coated silver (Ag@SiO2) nanoparticles were prepared and characterized by transmission electron microscope (TEM) and UV-vis absorption, and the nanoparticles were used as labels in sandwich-type immunosensor of Escherichia coli O157:H7 (E. coli O157:H7). The labels involved in immunoreaction were dissolved by mixed acid of hydrofluoric acid and nitric acid, and the released Ag(+) ions wer...
متن کاملRapid electrochemical detection of single influenza viruses tagged with silver nanoparticles
Using a state of the art nano-electrochemical technique, we show that a single virus ‘tagged’ with silver nanoparticles can be rapidly detected in real time at the single virus level. A solution containing a low concentration of influenza virus is exposed to silver nanoparticles which are adsorbed onto the virus surface, as revealed by UV-Vis spectroscopy and transmission electron microscopy. W...
