摘要：
本研究探讨了使用 Excoecaria agallocha 叶子作为插入硒纳米颗粒 (SeNP) 的生物模板。使用 SEM-EDX、TEM/HR-TEM 和 XRD 光谱研究等技术对合成的 SeNP 进行表征。研究发现，SeNPs在50μL/mL剂量时表现出最大的清洁能力，对DPPH自由基的抑制率为95%。然而，在 300μg/L 浓度下，72 小时内细胞吸收率仅限于 55%。合成的 SeNPs 还表现出对 MCF-7 乳腺癌细胞系的强烈细胞毒性作用，表明它们作为抗癌药物的潜力。需要进一步研究来充分探索这些新型纳米复合材料的潜力。版权所有 © 2024。由 Elsevier Inc. 出版。
This study investigates the use of Excoecaria agallocha leaves as a bio-template for the intercalation of Selenium nanoparticles (SeNPs). The synthesized SeNPs were characterized using techniques like SEM-EDX, TEM/HR-TEM, and XRD spectroscopic studies. The study found that SeNPs showed maximum cleaning ability at a dosage of 50 μL/mL, with 95% inhibition of DPPH radicals. However, cellular absorption was limited to 55% at concentrations of 300μg/L over a 72-hour period. The synthesized SeNPs also demonstrated a strong cytotoxic effect on MCF-7 breast cancer cell lines, indicating their potential as anti-cancer agents. Further research is needed to fully explore the potential of these novel nanocomposites.Copyright © 2024. Published by Elsevier Inc.
