Here we report the meteoric synthesis of luminescent nanomagnetic Fe₂O₃ (LNM Fe₂O₃) particles using green sources ie, microwave energy of 800 W and Hibiscus rosasinensis (H rosasinensis) leaf extract with high anti oxidant and anti cancer properties as an active surfactant. The microwave irradiation times for the synthesis of LNM Fe₂O₃ particles were optimized. Structural morphology, magnetic and optical properties of synthesized LNM Fe₂O₃ particles was studied using different analytical techniques. The data clearly indicated that H rosasinensis leaf extract‐mediated LNM Fe₂O₃ particles are spherical in shape with the presence of both α‐Fe₂O₃ and small amounts of ϒ ‐ Fe₂O₃ phases which have smaller size and larger surface area with slight agglomeration. Cytotoxic activities were performed on HCT‐116, HeLa and MCF‐7 cancer cell lines using MTT assay, antioxidant ability was determined using DPPH assay and bactericidal activity studies performed on Gram‐negative E coli bacteria and Gram‐positive bacteria Bacillus subtilis for the synthesized LNM Fe₂O₃ particles which were found to be highly efficient. Biological studies revealed that synthesized luminescent nanomagnetic Fe₂O₃ particles act as potential cytotoxic, antioxidant and bactericidal agent.

Fe2O3发光纳米粒子的流星合成：潜在的细胞毒性，抗氧化剂和杀菌剂

在这里，我们报道了使用绿色能源（即800 W的微波能量）和芙蓉玫瑰花（H rosasinensis）叶提取物的流态合成发光纳米磁性Fe ₂ O ₃（LNM Fe ₂ O ₃）颗粒的方法，该提取物具有很高的抗氧化剂和抗癌特性活性表面活性剂。优化了合成LNM Fe ₂ O ₃的微波辐射时间。使用不同的分析技术研究了合成的LNM Fe ₂ O ₃颗粒的结构形态，磁性和光学性质。数据清楚地表明，玫瑰红叶提取物介导的LNM Fe_2个ö ₃颗粒是球形与两者的α-Fe存在₂ ö ₃和少量的Υ -铁_2个ö ₃相具有更小的尺寸，并用轻微结块较大的表面积。使用MTT测定法对HCT-116，HeLa和MCF-7癌细胞系进行细胞毒活性，使用DPPH测定法测定抗氧化能力，并对革兰氏阴性大肠杆菌和枯草芽孢杆菌进行枯草芽孢杆菌杀菌活性研究LNM铁₂ O ₃被发现是高效的颗粒。生物学研究表明，合成的发光纳米磁性Fe ₂ O ₃颗粒具有潜在的细胞毒性，抗氧化剂和杀菌作用。
