| Summary: | In the present review the studies performed in the last two decades devoted to the electrodeposition of silver nanoparticles on the surface of carbon electrodes and their implementation in analytical chemistry are described. Usually graphite or glassy carbon electrodes (including screen-printed electrodes) are used, and the electrodeposition is performed from the solutions of potassium nitrate and silver nitrate during a few minutes. Silver nanoparticles or modified nanocomposites including silver nanoparticles are then immobilized on the surface of the electrodes, and obtained electrochemical sensors are capable to determine various compounds using different voltammetric methods with excellent selectivity and very good linearity range and precision. The described methods of analysis allow the determination of microgram quantities of hydrogen peroxide, glucose, cholesterol, methyl parathion, Pb2+ ions, chloramphenicol and metronidazole, doxorubicin, entacapone, tyrosine and tryptophan, lamotrigine, chromium (VI), antimony (III), trinitrotoluene, oligonucleotides and the bacterium Pseudomonas aeruginosa. |
