This study aimed to construct an alginate aerogel doped with carbon quantum dots and investigate the fluorescence properties of the composites. The carbon quantum dots with the highest fluorescence intensity were obtained using a methanol-water ratio of 1 : 1, a reaction time of 90 minutes, and a reaction temperature of 160 °C. The fluorescent carbon quantum dot sodium alginate-based aerogel (FCSA) obtained by compounding alginate and carbon quantum dots exhibited excellent fluorescence properties when the concentration of nano-carbon quantum dot solution was 10.0 vol%. By incorporating nano-carbon quantum dots, the fluorescence properties of the lamellar alginate aerogel can be easily and efficiently adjusted. The alginate aerogel decorated with nano-carbon quantum dots exhibits promising potential in biomedical applications due to its biodegradable, biocompatible, and sustainable properties.
本研究旨在构建一种掺杂碳量子点的海藻酸钠气凝胶，并研究复合材料的荧光特性。使用甲醇与水的比例为1∶1、反应时间为90分钟以及反应温度为160℃，获得了具有最高荧光强度的碳量子点。当纳米碳量子点溶液的浓度为10.0体积%时，通过将海藻酸钠与碳量子点复合得到的荧光碳量子点海藻酸钠基气凝胶（FCSA）表现出优异的荧光特性。通过掺入纳米碳量子点，可以轻松有效地调节层状海藻酸钠气凝胶的荧光特性。由于其具有可生物降解、生物相容性和可持续性等特性，用纳米碳量子点修饰的海藻酸钠气凝胶在生物医学应用中具有广阔的潜力。
