Nanocarrier systems have gained significant attention in recent decades as an alternative to conventional drug delivery methods, which often suffer from various limitations. In this study, FeO/chitosan/TiO nanoparticles were synthesized as a novel nanocarrier for targeted drug delivery. The loading efficiency and controlled release behavior of vancomycin from the nanocarrier were evaluated under in vitro conditions using HeLa cancer cells. The in vitro study of the drug release behavior showed that the implementation of a titania coating significantly diminishes the drug release rate. Specifically, approximately 90 ± 0.2% of the drug is released over a period of 16 h for samples without the titania coating, while samples with the coating exhibit a release time of 25 h. The MTT assay indicates that the application of TiO nanoparticles on the nanocarrier resulted in a decrease in cell viability from 90 ± 3% to 50 ± 2% at concentrations of 100 μg/mL and 500 μg/mL, respectively. These findings highlight the potential of the FeO/chitosan/TiO nanocarrier as an efficient system for controlled and targeted drug delivery applications.
近几十年来,纳米载体系统作为传统药物递送方法的替代方案而备受关注,传统方法往往存在各种局限性。在本研究中,合成了FeO/壳聚糖/TiO纳米颗粒作为一种新型的靶向药物递送纳米载体。使用HeLa癌细胞在体外条件下评估了万古霉素从纳米载体中的负载效率和控释行为。药物释放行为的体外研究表明,二氧化钛涂层的实施显著降低了药物释放速率。具体而言,对于没有二氧化钛涂层的样品,约90±0.2%的药物在16小时内释放,而有涂层的样品释放时间为25小时。MTT试验表明,在纳米载体上应用TiO纳米颗粒后,在浓度分别为100μg/mL和500μg/mL时,细胞活力从90±3%降至50±2%。这些发现突出了FeO/壳聚糖/TiO纳米载体作为一种用于控释和靶向药物递送应用的高效系统的潜力。
