• -decorated, SWCNT-based FETs for sensitive and selective detection of DA. This work is divided into two parts: First, we analyze the effect of ssDNA decoration of SWCNT on the FET response to DA, UA and DA–UA solution mixtures. Second, we interpret the sequence-dependent electrical response of both homo- and

• candidates to replace the hydrophobic fluorescent probes because they are resistant to photobleaching and exhibit strong fluorescence [33]. Excellent fluorescent probes based on CNDs were fabricated for a highly sensitive and selective detection of DNA molecules [24], Cu2+ ions [25] and dopamine [26]. The

• these gases at high temperatures has been demonstrated, selectivity between these gases remains a challenging task, as many interactions between the different analyte gases and the film surface can be manifested as a change in the position of the plasmon peak. Selective detection of gases can be

• exposures. They demonstrated the selective detection of H2 over CO, based on the differing response characteristics of the films in the different wavelength regions [20]. In another study, Gaspera et al. investigated the role of sol–gel-synthesized metal-oxide (NiO and TiO2) films that were coated over Au

• determined by statistical algorithms that show the greatest selective detection of the target analytes. In the current work, a Au–YSZ film has been fabricated through a layer-by-layer physical vapor deposition (PVD) procedure, and the response of the film to H2, CO and NO2 at 500 °C has been monitored by
