摘要

摘要以黄花Martynia annua全株水提物为原料，以银离子为原料合成银纳米粒子(Ag NPs)，并对其抑菌活性和细胞毒活性进行了研究。用索氏装置从非极性溶剂到极性溶剂进行萃取。首先，水萃取物通过初级植物化学试验进行分析，并用于银纳米粒子的合成。所得的银纳米粒子用紫外可见光谱进行了表征。光谱，XRD分析，FTIR光谱和HRTEM。在443nm处的紫外-可见光谱表面等离子体共振中心证实了银纳米粒子的形成。XRD分析和SAED图测定了金属银的结晶性质。HRTEM图像显示，银纳米粒子的形貌为10 ~ 25nm的球形。提取物和绿色合成的Ag NPs对细菌和真菌均有显著的抑菌活性，对人肺癌细胞株A549也有良好的细胞毒性。

Biosynthesis of silver nanoparticles using Martynia annua and its antimicrobial and cytotoxic activities

ABSTRACT The aim of present study, biosynthesis of silver nanoparticles (Ag NPs) was synthesized from silver ions using aqueous extract of the whole plant of Martynia annua and its Antimicrobial and Cytotoxic activities. The extraction is made by non-polar to polar solvent using Soxhlet apparatus. Initially, the aqueous (water) extract was analysed the primary phytochemical test and used for the synthesis of Ag NPs. The obtained Ag NPs were characterized using UV-vis. spectroscopy, XRD analysis, FTIR spectrum and HRTEM. The UV-vis spectroscopy surface Plasmon resonance centre at 443nm was confirmed the formation of Ag NPs. XRD analysis and SAED pattern was determining the crystalline nature of metallic silver. HRTEM image shows the morphology of Ag NPs contains spherical shapes with sizes 10-25nm. The extract and green synthesized Ag NPs have significant antimicrobial activity against both bacteria and fungi and also have good cytotoxicity against human lung cancer cell line A549 .

期刊介绍： Materials Technology: Advanced Performance Materials provides an international medium for the communication of progress in the field of functional materials (advanced materials in which composition, structure and surface are functionalised to confer specific, applications-oriented properties). The focus is on materials for biomedical, electronic, photonic and energy applications. Contributions should address the physical, chemical, or engineering sciences that underpin the design and application of these materials. The scientific and engineering aspects may include processing and structural characterisation from the micro- to nanoscale to achieve specific functionality.
