The proliferation of mosquito-borne diseases is a major health concern worldwide. An effective strategy to prevent the transmission of mosquito-borne diseases is using larvae control. Cinnamaldehyde, a substance from the cinnamon tree, is widely used in larvicide formulations, yet applications are limited due to the poor water solubility of cinnamaldehyde. Therefore, we prepared a sodium alginate–chitosan nanocomposite as a nanocarrier of cinnamaldehyde, and we tested the effect of this encapsulated cinnamaldehyde on Aedes aegypti larvae. The nanocomposites/cinnamaldehyde formulations were characterised by Fourier transform infrared spectroscopy and nuclear magnetic resonance, which evidenced encapsulation. A ratio of 150:1 w/w nanocomposite/cinnamaldehyde induced the highest encapsulation efficiency of 95.25%, a loading capacity of 81.42%. This extended the cinnamaldehyde release by 28 h and controlled mosquito larvae.

蚊媒疾病的扩散是全球主要的健康问题。防止蚊子传播疾病的有效策略是使用幼虫控制。肉桂醛是肉桂树中的一种物质，已广泛用于杀幼​​虫剂配方中，但由于肉桂醛的水溶性差，因此应用受到限制。因此，我们制备了藻酸钠-壳聚糖纳米复合材料作为肉桂醛的纳米载体，并测试了这种封装的肉桂醛对埃及伊蚊的影响。幼虫。纳米复合材料/肉桂醛配方的特征在于傅立叶变换红外光谱和核磁共振，证明了封装作用。纳米复合材料/肉桂醛的比例为150：1 w / w，诱导的最高包封效率为95.25％，负载量为81.42％。这使肉桂醛释放延长了28小时，并控制了蚊虫幼虫。
