“…However, much less attention has been paid to the anodic ECL of CDs. Yu's group observed that the CDs obtained from hydrothemal treatment of GO could produce strong anodic ECL signal in the presence of H 2 O 2 as coreactant [218]. The authors argued that the anodic ECL signal was caused by the electron transfer between the electro-generated R…”

“…In their another work, CDs were coated on ZnO nanoshpere to form ZnO@CDs hybrid and used for the detection leukemia cells, accordingly to a similar principle used in the detection of MCF-7 cells [214]. They have also proposed an ECL aptamer sensor for adenosine triphosphate (ATP) determination based on the ECL behaviors of CDs [218]. CDs contained abundant carboxyl groups were first covalently bind to the amino-functionalized SiO 2 nanoparticles to obtain SiO 2 /CDs composites, which were subsequently incubated with an amino group functionalized single strand DNA (ssDNA2).…”

Carbon based dots (CDs) composed of sp 2 carbon structures and surface functional groups are a new kind of carbon nanomaterials, exhibiting unique luminescent properties due to the quantum confinement and edge effects. This chapter introduces CDs in detail from their synthetic strategies, morphological and structural characteristics, luminescent properties and mechanisms, and sensing applications. The synthesis methods are summarized as "top-down" and "bottomup" approaches. Luminescent properties discussed include photoluminescence, upconversion luminescence, chemiluminescence, electrochemiluminescence. Sensing applications mainly refer to the chemical and biological sensors based on the luminescent properties of CDs. This chapter provides an overview of the research field and gives future perspectives for developing the exciting materials.

“…1C. The characteristic absorption peaks for C=C at 1571 cm -1 and C-C at 1234 cm -1 were observed, indicating the existence of delocalized π-electrons in N-GQDs molecules (Lu et al, 2013). The absorption peaks around 3205 cm -1 and 1040 cm -1 were assigned to the stretching vibrations of N-H and N-C groups, respectively (Hu et al, 2013).…”

Metal nanoparticles, with a wide range of applications in catalysis and sensing, have structural and electronic properties that differ from those of their bulk macroscopic counterparts. Electrochemical techniques are of particular interest in the study of metal nanoparticles because electrons may undergo quantum confinement effects which are reflected in their electrochemical behavior, resulting, ultimately, in three distinguishable voltammetric regimes: bulk continuum, quantized double-layer charging, and molecule-like. Similarly, semiconductor nanoparticles (quantum dots, QDs) are receiving considerable attention due to their high fluorescence, which makes them of interest for biological and medical applications, among others. The semiconductor bulk materials possess defect states that originate from impurities, divacancies, or surface reactions as a result of their synthesis. Voltammetric features provide information on bandgap energy, the position of conduction and valence band edges, and the position of defect sites as well as on the interaction with the capping ligand. This chapter is devoted to provide a critical view of the current state of the art in the electrochemistry of such systems.
