What are CdSe/ZnS qdots?
9 answers
CdSe/ZnS quantum dots (QDs) are colloidal semiconductor nanocrystals that exhibit unique optical properties, making them highly suitable for a wide range of applications in optoelectronics and biotechnology. The core of these quantum dots is made of cadmium selenide (CdSe), which is responsible for their light-emitting properties, while the shell is composed of zinc sulfide (ZnS), which enhances the optical stability and efficiency of the quantum dots. This core/shell structure is crucial for improving the quantum yield (QY), which is a measure of the efficiency of photon emission following photon absorption. The synthesis and structural control of CdSe/ZnS QDs allow for the tuning of their fluorescence properties by adjusting parameters such as the size of the core and the thickness of the shell. This tunability is due to the quantum confinement effect, where the electronic and optical properties of the quantum dots change with their size. The application of external comprehensive pressure can further modify the optical band gap of these quantum dots, demonstrating their versatile adaptability. CdSe/ZnS QDs are embedded in various matrices, such as polymethyl methacrylate (PMMA), to protect them during device fabrication processes and to enhance their photoluminescence and radiative mechanisms. They are also combined with other materials, such as hydrophobic tetraphenylporphyrin (TPP) molecules, to form nanocomposites that exhibit enhanced singlet oxygen generation, beneficial for applications like sensing and bio-imaging. Their exceptional optical properties, including size-tunable emission, high quantum efficiency, and stability, make CdSe/ZnS QDs ideal candidates for use in light-emitting devices (LEDs), solar concentrators, single-photon sources, and fluorescent labeling materials in bio-imaging and detection applications.

Is cbd more stable against bioprocesses than other cannabinoids?
10 answers
The stability of cannabidiol (CBD) compared to other cannabinoids against bioprocesses varies depending on the conditions and matrices involved. For instance, in biological specimens such as human whole blood, synthetic cannabinoids like AB-Fubinaca, AB-Pinaca, and UR-144 showed relative stability under various storage conditions, whereas XLR-11 significantly degraded, suggesting that not all cannabinoids share the same stability profile. However, this study did not directly compare CBD's stability to these synthetic cannabinoids. CBD's stability in different solvents under thermal and photochemical conditions indicates it is relatively unstable, especially when considering its conversion into psychotropic cannabinoids under certain conditions. This instability is further highlighted in pharmaceutical preparations and commercial products, where CBD degradation products were identified under various conditions. In contrast, a study focusing on CBD in solid powder form and dissolved in sunflower oil found that CBD powder was significantly more stable than CBD in oil solution, emphasizing the impact of the formulation on CBD's stability. Comparatively, the stability of THC and CBD in oral fluid on FLOQSwabs® showed similar degradation profiles under different storage conditions, suggesting that CBD and THC have comparable stability in this specific matrix. Blood and plasma cannabinoid stability studies also did not provide sufficient data to assess CBD's stability, indicating a gap in direct comparisons between CBD and other cannabinoids in these biological matrices. Research on e-cigarette liquids containing CBD demonstrated negligible formation of THC during the smoking process, suggesting that CBD is stable against thermal degradation to THC in this context. However, the debate on CBD's conversion to psychotropic THC under in vivo conditions remains, with most studies suggesting that CBD does not convert to THC in vivo, although it can degrade into psychotropic products in acidic environments. Preclinical models have shown that cannabinoids, including CBD, exhibit cytotoxic effects against cancer cells, with studies indicating that the stability and efficacy of cannabinoids can vary significantly depending on the nature of the cancer cells and test conditions. The development of highly stable and water-soluble CBD microcapsules aims to improve the bioavailability and action effect of CBD, indicating efforts to enhance CBD's stability for industrial applications. Lastly, the evaluation of CBD's skin permeability and its formulations highlighted the influence of surfactants and pH on CBD's stability, suggesting that CBD's stability can be optimized for dermatological applications. In summary, while CBD shows varying degrees of stability across different studies and conditions, direct comparisons with the stability of other cannabinoids are limited and context-dependent. The available data suggest that CBD's stability is influenced by factors such as formulation, storage conditions, and the presence of acidic catalysts, rather than being inherently more or less stable against bioprocesses compared to other cannabinoids.
