具有不同形貌的新型纳米颗粒的生物合成,这对他们的生物能力有很好的影响,在纳米技术领域引起了越来越多的关注。真菌提取物中存在的生物活性化合物,细菌,植物和藻类负责纳米粒子的合成。与其他生物资源相比,棕色海藻也可用于将金属离子转化为金属纳米颗粒,因为存在更丰富的生物活性化学物质。碳水化合物,蛋白质,多糖,维生素,酶,颜料,棕色海藻中的次生代谢产物起到自然还原的作用,capping,和纳米粒子合成中的稳定剂。大约有2000种海藻主导着海洋资源,但只有少数报道了纳米粒子的合成。生物活性化学物质在生物合成的金属纳米颗粒中的存在赋予生物活性。褐藻生物合成的金属和非金属纳米颗粒因其不同的理化性质而具有不同的生物活性。与陆地资源相比,海洋资源对纳米粒子合成的探索并不多。为了确认它们的形态,使用表征方法,如吸收分光光度计,X射线衍射,傅里叶变换红外光谱,扫描电子显微镜,和透射电子显微镜。这篇综述试图包括褐藻在金属和非金属纳米粒子合成中的重要作用,以及合成方法和生物应用,如抗癌,抗菌,抗氧化剂,抗糖尿病,和其他功能。
The biosynthesis of novel nanoparticles with varied morphologies, which has good implications for their biological capabilities, has attracted increasing attention in the field of nanotechnology. Bioactive compounds present in the extract of fungi, bacteria, plants and algae are responsible for nanoparticle synthesis. In comparison to other biological resources, brown
seaweeds can also be useful to convert metal ions to metal nanoparticles because of the presence of richer bioactive chemicals. Carbohydrates, proteins, polysaccharides, vitamins, enzymes, pigments, and secondary metabolites in brown
seaweeds act as natural reducing, capping, and stabilizing agents in the nanoparticle\'s synthesis. There are around 2000 species of seaweed that dominate marine resources, but only a few have been reported for nanoparticle synthesis. The presence of bioactive chemicals in the biosynthesized metal nanoparticles confers biological activity. The biosynthesized metal and non-metal nanoparticles from brown
seaweeds possess different biological activities because of their different physiochemical properties. Compared with terrestrial resources, marine resources are not much explored for nanoparticle synthesis. To confirm their morphology, characterization methods are used, such as absorption spectrophotometer, X-ray diffraction, Fourier transforms infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. This review attempts to include the vital role of brown seaweed in the synthesis of metal and non-metal nanoparticles, as well as the method of synthesis and biological applications such as anticancer, antibacterial, antioxidant, anti-diabetic, and other functions.
