In this study, we developed sodium alginate-chitosan hydrogels using a microwave-assisted synthesis method, aligning with green chemistry principles for enhanced sustainability. This eco-friendly approach minimizes chemical use and waste while boosting efficiency. A curcumin:2-hydroxypropyl-β-cyclodextrin complex was incorporated into the hydrogels, significantly increasing the solubility and bioavailability of curcumin. Fourier Transform Infrared Spectroscopy (FTIR) analysis confirmed the structure and successful incorporation of curcumin, in both its pure and complexed forms, into the polymer matrix. Differential scanning calorimetry revealed distinct thermal transitions influenced by the hydrogel composition and physical cross-linking. Hydrogels with higher alginate content had higher swelling ratios (338%), while those with more chitosan showed the lowest swelling ratios (254%). Scanning Electron Microscopy (SEM) micrographs showed a porous structure as well as successful incorporation of curcumin or its complex. Curcumin release studies indicated varying releasing rates between its pure and complexed forms. The chitosan-dominant hydrogel exhibited the slowest release rate of pure curcumin, while the alginate-dominant hydrogel exhibited the fastest. Conversely, for curcumin from the inclusion complex, a higher chitosan proportion led to the fastest release rate, while a higher alginate proportion resulted in the slowest. This study demonstrates that the form of curcumin incorporation and gel matrix composition critically influence the release profile. Our findings offer valuable insights for designing effective curcumin delivery systems, representing a significant advancement in biodegradable and sustainable drug delivery technologies.
在本研究中,我们采用微波辅助合成法制备了海藻酸钠-壳聚糖水凝胶,符合绿色化学原则以提高可持续性。这种环保方法在提高效率的同时,最大限度地减少了化学物质的使用和废物产生。将姜黄素:2-羟丙基-β-环糊精复合物掺入水凝胶中,显著提高了姜黄素的溶解度和生物利用度。傅里叶变换红外光谱(FTIR)分析证实了姜黄素以其纯形式和复合形式成功掺入聚合物基质的结构。差示扫描量热法揭示了受水凝胶组成和物理交联影响的明显热转变。海藻酸钠含量较高的水凝胶具有较高的溶胀率(338%),而壳聚糖含量较高的水凝胶溶胀率最低(254%)。扫描电子显微镜(SEM)显微照片显示了多孔结构以及姜黄素或其复合物的成功掺入。姜黄素释放研究表明其纯形式和复合形式之间的释放速率不同。以壳聚糖为主的水凝胶中纯姜黄素的释放速率最慢,而以海藻酸钠为主的水凝胶释放速率最快。相反,对于包合物中的姜黄素,壳聚糖比例越高,释放速率越快,而海藻酸钠比例越高,释放速率越慢。本研究表明,姜黄素的掺入形式和凝胶基质组成对释放曲线有至关重要的影响。我们的研究结果为设计有效的姜黄素递送系统提供了有价值的见解,代表了可生物降解和可持续药物递送技术的重大进展。
