In recent years, new carbonized nanomaterials have emerged in imaging, sensing, and various biomedical applications. Published literature shows that carbon dots (CDs) been explored more extensively than any other nanomaterials. However, its polymeric version, polymer (CPDs), did not get much attention. The non-conjugated single-particle CPDs all the merits of CDs, such as photoluminescent prope...

Carbon quantum dots (CDs) are “small” carbon nanostructures with excellent photoluminescence properties, together low-toxicity, high biocompatibility, dispersibility in water as well organic solvents. Due to their characteristics, CDs have been studied for a plethora of applications biosensors, luminescent probes photodynamic and photothermal therapy, fluorescent inks many more. Moreover, the p...

(51)Cr-labeled, superparamagnetic, iron oxide nanoparticles ((51)Cr-SPIOs) and (65)Zn-labeled CdSe/CdS/ZnS-quantum dots ((65)Zn-Qdots) were prepared using an easy, on demand, exchange-labeling technique and their particokinetic parameters were studied in mice after intravenous injection. The results indicate that the application of these heterologous isotopes can be used to successfully mark th...

The present work introduces coordinative binding of CuII ions with both amino-functionalized silica nanoparticles (SNs) and green-emitting carbon dots (CDs) as the pregrequisite for CuII-assisted self-assembly CDs at surface SNs. produced composite SNs exhibit stable in time stimuli-responsive green fluorescence derived from assemblage CDs. response is sensitive to complex formation glutathione...

Various types of fluorescent carbon nanoparticles, often called dots (CDs), are synthesized by different polycondensation methods: microwave irradiation, hydrothermal conditions or solution chemistry at ambient temperature with subsequent chemical functionalization. The CDs deposited on TiO2 films to be probed as electron transport layers in perovskite photovoltaics and the anode for photoelect...

Colloidal semiconductor nanocrystals are receiving considerable attention as novel luminescent biological probes due to their unique optical properties,. The chemically synthesized nanoparticles are small in size, very bright and photostable. The advantages with respect to conventional fluorophores consist mainly in narrow band edge emissions, tunable with the nanocrystal size, broad absorption...

This paper presents the synthesis of aqueous cadmium sulfide (CdS) quantum dots (QDs) and silica-encapsulated CdS QDs by reverse microemulsion method and utilized as targeted bio-optical probes. We report the role of CdS as an efficient cell tag with fluorescence on par with previously documented cadmium telluride and cadmium selenide QDs, which have been considered to impart high levels of tox...

   In this study, cadmium sulfide nanoparticles (CdS NPs) were prepared, characterized and used as a new adsorbent for simultaneous removal of Pb(II) and Cu(II) ions from aqueous solutions. Using a batch adsorption method, the effects of solution pH, contact time, adsorbent dose, and temperature were studied and optimized. Removal efficiencies, higher than 98% were obtained for both the met...

Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields. A large portion of these properties find their connection to optics and photonics. In the context of ...
