Voltammetric determination of polyphenolic content in pomegranate juice using a poly(gallic acid)/multiwalled carbon nanotube modified electrode
Beilstein J. Nanotechnol. 2016, 7, 1104–1112, doi:10.3762/bjnano.7.103
- [6]. A sensitive and reliable method was developed using a differential pulse polarographic method for determination of GA in fruit juices with a detection limit of 0.3 µM [7]. Electrochemical sensors based on a carbon paste electrode modified with SiO2 nanoparticles [8] and carbon nanotubes [9][10
- representatives of nanomaterials used in the construction of electrochemical sensors with good performance. Multiwalled carbon nanotubes (MWCNTs) were selected due to their advantages such as rapid electron transfer rate and high electrocatalytic activity. The glassy carbon working electrode was electrochemically

- the electrochemical conditions (such as voltage, intensity, or scan rate), and by other experimental conditions such as the nature and concentration of the doping agent or the nature of the substrate [4]. This versatility can be used to better control the development of electrochemical sensors with
- sensing properties of the Ppy/AuNPs films directly depend on the polymerization conditions. However, the influence of the polymerization conditions in the properties of Ppy/AuNPs electrodes has not been yet studied. One of the fields where electrochemical sensors are having an important success is in the
Synthesis, characterization and in vitro biocompatibility study of Au/TMC/Fe3O4 nanocomposites as a promising, nontoxic system for biomedical applications
Beilstein J. Nanotechnol. 2015, 6, 1677–1689, doi:10.3762/bjnano.6.170
- particularly anticipated in the fields of electrochemical sensors and biosensors, where Au nanoparticles play a fundamental role as labels or platforms for immobilization. In this respect, our results suggest that enhanced signal amplification and increased magnetic separation efficiency are likely. In

- temperatures [18]) thus enabling the development of low-power sensors [13][19]. This is essential for achieving long-life, battery-operated, wearable detectors. Furthermore, carbon nanotube sensors can be easily miniaturised, which is not the case for electrochemical sensors [20]. Pristine carbon nanotubes are
Properties of plasmonic arrays produced by pulsed-laser nanostructuring of thin Au films
Beilstein J. Nanotechnol. 2014, 5, 2102–2112, doi:10.3762/bjnano.5.219
- structures showing the SPR effect, Au NPs play important role in the construction of electrochemical sensors [55]. This is confirmed by numerous results obtained with the use of Au-modified, conducting oxide materials, such as indium tin oxide, fluorine tin oxide and others. In particular, the ITO substrate
Nanocavity crossbar arrays for parallel electrochemical sensing on a chip

- limits; Recently, Lemay’s group reported the ultimate detection limit by sensing at molecular resolution inside a nanofluidic redox cycling device [14][15][16]. Besides the advantages of electrochemical amplification, redox cycling sensors allow for the formation of large, dense arrays of electrochemical
- sensors that are highly desirable for applications such as on-chip parallel biosensing or the detection of chemical communication in a neuronal network. This can be achieved via the organization of feed lines in a perpendicular arrangement. Individual sensors are then located at each of the feed line

- -VNTs forests to develop electrochemical sensors for the detection of bromate. Brown et al. [100] investigated the potential use of VA-CNTs as neural stimulation electrodes. They performed flash oxidation (short exposition time of 20 min) of the VA-CNTs in O2 (100 sccm) at various temperatures (between

Beilstein J. Nanotechnol. 2013, 4, 20–31, doi:10.3762/bjnano.4.3
- flexibility not possible in a singly or multiply “coated” metal-oxide interface. Metal-oxide sensors (Figure 9) (when compared also to electrochemical sensors) are slightly less costly to produce; however, concerns may include poor sensitivity, high power requirements, and most importantly, the need to

- site of several biomacromolecules and the electrode surface can also be set up with the aid of CNTs [16][17]. Because the application of CNTs can dramatically improve the sensitivity of electrochemical sensors, more and more analytical chemists have focused their attention on CNTs-modified electrodes
