What are the relationship between photoluminescence characteristics to toxicity level of carbon dots?
5 answers
The relationship between the photoluminescence characteristics and toxicity level of carbon dots (CDs) is multifaceted, influenced by factors such as synthesis methods, surface functionalization, and environmental conditions. CDs exhibit a wide range of desirable properties, including excellent photoluminescence, photostability, and water solubility, which make them suitable for various applications in bioimaging and drug delivery. However, the toxicity levels of CDs can vary significantly depending on these characteristics. Photoluminescence properties, such as emission wavelength and quantum yield, are determined by the size, surface functional groups, and crystallinity of CDs. For instance, graphene quantum dots (GQDs) prepared through specific synthesis methods showed high fluorescence quantum yield and strong photoluminescence, indicating good biocompatibility for cell imaging and biolabeling applications. Similarly, CDs synthesized from green precursors demonstrated magnificent biocompatibility and excitation wavelength-dependent photoluminescence, making them potential candidates for sensing toxic heavy-metal ions in water sources. The surface functionalization of CDs plays a crucial role in their interaction with biological systems. CDs with abundant hydroxyl functional groups on their surface exhibited exceptional biocompatibilities to various biological entities, including human cell lines, indicating that surface functionality could mitigate toxicity. Conversely, photodegradation of CDs under illumination can lead to the formation of cytotoxic molecules, highlighting the importance of photostability in determining the cytocompatibility of CDs. Environmental conditions, such as light exposure, can also influence the toxicity of CDs. Laboratory-synthesized CDs irradiated with light degraded into molecules toxic to human cells, suggesting that photodegradation-induced cytotoxicity is a critical factor to consider. Furthermore, the synthesis method and starting materials can impact the toxicity profile of CDs, as demonstrated by the non-toxic nature of CDs prepared using a mixed-acid treatment, which showed no noticeable signs of toxicity in animal models. In summary, the photoluminescence characteristics of CDs, including their synthesis method, surface functionalization, and stability under environmental conditions, are closely related to their toxicity levels. Understanding these relationships is crucial for the safe design and application of CDs in biomedical and environmental fields.
