“…Graphite has carbon-carbon bond with sp 2 hybridization and weak bond energy amongst the head-to-head layers and bond with in and out of plane of p-orbitals respectively [7]. Graphene is a well-known material which shows exceptional properties such as thermal, electrical and mechanical which are due to its unique structure which are an atom thick.…”

“…A new trend in the biosensor construction is the use of nanomaterials which exhibit unique and attractive chemical, physical and electronic properties (Park et al, 2009;Bonanni and del Valle, 2010;Hepel and Zhong, 2012;Krejcova et al, 2012;Luz et al, 2013;Krejcova et al, 2014). Various nanomaterials have been recently used as an electrode platform in highly sophisticated electroanalytical biosensing devices (Hepel & Zhong, 2012;Hernandez & Ozalp, 2012).…”

Electrochemical biosensors have emerged as reliable analytical devices suitable for pathogen detection. Low cost, small sample requirement and possibility of miniaturization justifies their increasing development. Thus, we report in this review on the state of the art of avian influenza virus detection with genosensors and immunosensors working by an electrochemical mode. Their working principles focusing on the physical properties of the transducer, the immobilization chemistry, as well as new trends including incorporation of nanoparticles will be presented. Then, we critically review the detection of avian influenza virus in the complex matrices that use electrochemical biosensors and compare them with traditionally applied methods such as ELISA or Western blot.

“…Zinc oxide and copper oxide nanostructures have been already using in different types of gas [39,40], heavy metal ions [39,[41][42][43] and bio-sensors [44][45][46][47][48] The formation of CuO nanostructures occurs according to the dissolutionsecondary precipitation mechanism in two stages, when copper hydroxide is formed at the beginning of the growth process, followed by its oxidation. The growth mechanism is described in the articles [49][50][51][52].…”

Glyphosate, commonly known by its original trade name Roundup™, is the world’s most widely used herbicide. Glyphosate and it metabolites have profound negative environmental impact and long-term toxicity risk including cancerogenity, genotoxicity, endocrine disruption even at concentration levels too low to have a herbicidal effect. Therefore, the detection of these pollutants in low concentrations is an actual and important task. To increase the sensitivity of the sensor, nanostructures were used. To analyze the presence of glyphosate and its metabolites in rye juice, two groups of samples were selected. In the first case, glyphosate at different concentrations was added to the water for irrigation on the first day and then the samples were watered with pure water for 7 days. In the second case, rye was watered with pure water for all 8 days, and glyphosate was artificially added just before the measurement. The obtained samples were studied by the DPV employing nanostructured working electrode. To analyze changes in the DNA sequence, a PCR product obtained from samples of the first group was electrochemically studied. To confirm the results obtained, an electrophoresis method was also applied. The results indicate that the DPV signal obtained from samples with artificially added glyphosate has significant differences compared to the signal obtained from the juice of plants absorbing glyphosate in a natural way during growth. However, in both cases, CuO nanostructure based sensor detects the presence of glyphosate or its metabolites compared with the control sample. The experiment also found significant changes in the DNA caused by exposure with glyphosate during rye growth process of rye sprouts.
