Evaluation of the novel nanoparticle material – CdSe quantum dots on Chlorella pyrenoidosa and Scenedesmus obliquus: Concentration-time-dependent responses

Ultraprecise control over the photophysical properties of novel amino acid functionalized CdTeS quantum dots and their effect on the emission of yellow-emissive carbon dots

“…11–13 However, the composition of binary quantum dots is invariable and the only way to control the photophysical properties of binary quantum dots is to control the size of the nanocrystal. 11–13 In the last decade, the focus of studies on cadmium-based quantum dots has started to shift toward ternary and quaternary quantum dots. 16–24 Researchers are very intrigued by developments in ternary/quaternary quantum dots as control over the composition of ternary/quaternary quantum dots allows researchers to control the photophysical properties of quantum dots with a different approach in addition to controlling the photophysical properties by controlling the size of the quantum dots.…”

“…9,10 These unique nanomaterials are versatile materials in biotechnology due to their two superior properties: (1) excellent photophysical properties such as high fluorescence quantum yield and broad absorption bands and (2) modifiable nanocrystal surface with different biomolecules. [11][12][13] Therefore, obtaining ultraprecise control over the photophysical properties of quantum dots and modifying the surface of quantum dots with biomolecules without losing their excellent photophysical properties are amongst the muchstudied topics, and developing novel biomolecule-functionalized cadmium-based quantum dots is still a challenge. 14,15 Quantum dots are fluorescent nanocrystals whose photophysical properties can be controlled by controlling size of the nanocrystal and/or composition of the nanocrystal.…”

[11][12][13] Binary core and core-shell cadmium chalcogenide quantum dots are of interest because their nanocrystal size can be controlled easily by bottom-up synthesis methods.

Toxicity of quantum dots on target organs and immune system

“…Due to their unique optical properties, QDs have attracted much attention to various fields in recent years and have shown huge application potential for the field of biomedicine (Javanbakht & Shaabani, 2019;Yu et al, 2020). However, with the wide applications, QDs will inevitably enter the ecosystem during their production and disposition (Lowry et al, 2012;Yan et al, 2019;Yao et al, 2018). In fact, QDs have been detected in freshwater lake (Wang & Nowack, 2018).…”
