Abstract

Nanotechnology is one of the advanced technologies that have almost universal implications in every field of science. The importance is due to the unique properties of nanoparticles; however, green synthesized nanoparticles are considered eco-friendly. The current project was rationalized to prepare green-synthesized biogenic Dcne. silver nanoparticles (Pe-AgNPs) and poly (ethylene glycol) methacrylate coated AgNPs nanocomposites (PEGMA-AgNPs) with higher potential for their application in plant tissue culture for enhancing the biomass of calli. The increased biomass accumulation (17.61 g/3 plates) was observed on a medium containing virgin Pe-AgNPs 40th days after incubation, while the maximum increase was found by supplementing virgin Pe-AgNPs and PEGMA capped AgNPs (19.56 g/3 plates), compared with control (12.01 g/3 plates). In this study, PEGMA capped AgNPs supplementation also induced the maximum increase in total phenolics content (2.46 mg GAE/g-FW), total flavonoids content (3.68 mg QE/g-FW), SOD activity (53.78 U/ml protein), GSH content (139.75 μg/g FW), antioxidant activity (54.3 mg AAE/g FW), FRAP (54 mg AAE/g FW), and DPPH (76.3%) in calli compared with the control. It was concluded that virgin Pe-AgNPs and PEGMA capped AgNPs (hybrid polymer) are potent growth regulator agents and elicitors that can be exploited in the biotechnology field for growth promotion and induction of essential bioactive compounds and secondary metabolites from various commercially important and medicinally valuable plants such as without laborious field cultivation.

摘要

纳米技术是一种先进技术，几乎在科学的各个领域都有广泛影响。其重要性源于纳米颗粒的独特性质；然而，绿色合成的纳米颗粒被认为是生态友好的。当前项目旨在制备绿色合成的生物源Dcne。银纳米颗粒（Pe-AgNPs）和聚（乙二醇）甲基丙烯酸酯包覆的AgNPs纳米复合材料（PEGMA-AgNPs），它们在植物组织培养中具有更高的应用潜力，可用于提高愈伤组织的生物量。在含有原始Pe-AgNPs的培养基上培养40天后，观察到生物量积累增加（17.61克/3个平板），而与对照（12.01克/3个平板）相比，添加原始Pe-AgNPs和PEGMA包覆的AgNPs时生物量增加最大（19.56克/3个平板）。在本研究中，添加PEGMA包覆的AgNPs还使愈伤组织中的总酚含量（2.46毫克GAE/克鲜重）、总黄酮含量（3.68毫克QE/克鲜重）、超氧化物歧化酶活性（53.78单位/毫升蛋白质）、谷胱甘肽含量（139.75微克/克鲜重）、抗氧化活性（54.3毫克AAE/克鲜重）、铁还原抗氧化能力（54毫克AAE/克鲜重）和二苯基苦味酰基自由基清除率（76.3%）相比对照有最大程度的增加。得出的结论是，原始Pe-AgNPs和PEGMA包覆的AgNPs（杂化聚合物）是有效的生长调节剂和诱导剂，可在生物技术领域用于促进生长以及诱导各种具有商业重要性和药用价值的植物产生必需的生物活性化合物和次生代谢产物，而无需进行费力的田间种植。
