Since the electrogenerated chemiluminescence (ECL) of silicon nanoparticles (NPs) was reported in 2002, miscellaneous nanomaterials with various sizes and shapes have been employed as ECL nanoemitters for bioanalysis. Elucidation of the ECL derivation from these nanoemitters and pertinent biofunctionalization with multitudinous biomolecules can offer excellent ECL signal-transduction platforms for fabricating novel biosensing devices. In this review, we comprehensively describe retrospective and recent advances in NPs-based ECL and related biosensing methodologies, and review their analytical applications in the detection of small biological molecules, enzymatic sensing, immunoassay, DNA analysis and cytosensing.

“…Among these materials, CdS, one of the most important II-VI group semiconductors, has potential applications for light-emitting diodes, solar cells, optoelectronics and photocatalysts [3]. It has a direct band gap of 2.5 eV for bulk hexagonal wurtzite structure [3], and a Bohr exciton diameter around 5.8 nm [4].…”

“…As a result, it has been successfully used to synthesize a variety of nano singles and composite materials including core-shell structure. Currently, lots of core-shell structure nanocomposites have been synthesized by the cavitation of sonochemical synthetic method, e.g., Au@Pd (Mizukoshi et al 2000), Au@Ag (Anandan et al 2008), Fe-Ni@iron oxide (Douvalis et al 2012), Fe 3 O 4 @SiO 2 (Morel et al 2008), CaCO 3 @SiO 2 (Virtudazo et al 2013), CdSe@ZnS (Murcia et al 2006), ZnO@CdS (Geng et al 2011), SiO 2 @CdS (Siva et al 2014), and PS@ZnS (Breen et al 2001). However, few studies have been reported involving PS@CdS nanoparticles synthesized via the sonochemical method.…”

In this study, spherical polystyrene (PS)@CdS core-shell structure nanoparticles (CSNPs) were prepared by sonochemical method. The influences of the surfactant PVP, the order of adding precursors, the molar ratio of S/Cd, and the reaction time on structure were carefully studied. Results of SEM, TEM, EDS, XRD, and FT-IR showed that the as-prepared nanohybrids have a typical coreshell structure with 260 nm core and a uniform shell with thickness ranging from 10 to 30 nm, both PVP and the order of adding precursors were the controlling parameters. In addition, the as-synthesized PS@CdS CSNPs exhibited much higher photocatalytic activity for RhB under visible light irradiation compared with pure CdS, which should be attributed to their synergic effect between core and shell, amount of hydroxyl groups on the surface, good monodispersity, and so on. Besides, the production of photogenerated hydroxyl radical ( • OH) was in accordance with the RhB decolorization efficiency from the prepared PS@CdS CSNPs. It indicated that • OH was the main active oxygen species in the photocatalytic process.
