Surface modification of nanoparticles for biological applications is receiving enormous interest among the research community due to the ability to alchemy the toxic nanoparticles into biocompatible compounds. In this study, the agrowastes of Moringa oleifera and Coriandrum sativum were used to surface modify the magnesium oxide nanoparticles and ferric oxide nanoparticles respectively. The agrowaste amended magnesium oxide nano particles (AMNP) and agrowaste amended ferric oxide nanoparticles (AFNP) were characterized using scanning electron microscope, X-ray diffractometer, Fourier transformed-infra red spectroscope to justify the formation and surface modification of nanoparticles with the organic functional groups from the agro wastes. The surface modified nano particles were tested for their biocompatibility and ability to treat the chlorosis in Glycine max. On comparison between the two metal based nanoparticles, AMNP exhibited better chlorosis treating ability than the AFNP. Both the nano particles showed increased potency at minimal amount, 30 μg and the higher concentrations till 125 μg exhibited down run of the potency which was again enhanced from 250 μg of nanoparticle treatment to plants. Further the surface modified nanoparticles were assessed for biocompatibility on human embryonic kidney (HEK-293) cell line which proved that the cell lines are non-toxic to normal human cells. The size of the particles and the concentration is suggested to be responsible for the effective chlorosis treatment and the organic functional groups responsible for the reduction of toxicity of the particles to the plants.

Fe2O3和MgO纳米粒子表面活性剂的改性以治疗大豆中的萎黄病。

由于能够将有毒纳米颗粒炼成生物相容性化合物，因此用于生物应用的纳米颗粒的表面改性在研究界引起了极大的兴趣。在这项研究中，辣木和香菜的生长激素分别用于表面修饰氧化镁纳米粒子和氧化铁纳米粒子。使用扫描电子显微镜，X射线衍射仪，傅立叶变换红外光谱仪对农残改性的氧化镁纳米颗粒（AMNP）和农残改性的氧化铁纳米颗粒（AFNP）进行表征，以证明具有有机功能的纳米颗粒的形成和表面改性从农业废物中分类。测试了表面改性的纳米颗粒的生物相容性和处理大豆最大绿化病的能力。在两种基于金属的纳米颗粒之间的比较中，AMNP表现出比AFNP更好的褪绿处理能力。两种纳米颗粒均以最小的30μg的量显示出增加的效价，而直到125μg的较高浓度都显示出下降的效价，这又从250μg纳米颗粒处理到植物得到了增强。进一步评估了表面修饰的纳米颗粒在人胚胎肾（HEK-293）细胞系上的生物相容性，证明该细胞系对正常人细胞无毒。
