• biosensor (Figure 6a and Figure 6b). Selective detection of H2O2 The simplicity of design and the ease of layer-by-layer modification make this surface an excellent electrochemical sensing platform for hydrogen peroxide detection. Figure 6c shows typical chronoamperometric responses of the ferrocene moiety

• -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

In another study, Gaspera et al. investigated the role of sol–gel-synthesized metal-oxide (NiO and TiO2) films that were coated over Au

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
