In this project, silver‑platinum (AgPt) nanoparticles were prepared by using the Crocus sativus L. plant ethanolic extract. The AgPt nanoparticles were characterized by applying the various method as ultraviolet-visible and infrared spectroscopy, electron microscopy, and X-ray diffraction analysis. The morphology structural indicated that the AgPt nanoparticles were spherical particles with diameter about 36.0 nm. The FTIR spectroscopy shows the efficient stabilization of the AgPt nanoparticles by phytoconstituents. The Ag and AgPt nanoparticles have polyphenolic content, lower than the flavonoids and proanthocyanins contents. The AgPt nanoparticles depicted the highest antioxidant properties compared to the Ag nanoparticles and ascorbic acid. The results showed that the AgPt nanoparticles had a high antioxidant properties. In addition, the AgPt nanoparticles demonstrated the substantial antimicrobial and cytotoxic activities against pathogenic microbes and MCF-7 breast cancer cell line. The environmental chemistry analysis depicts that methyl orange can be degraded from water by catalytic degradation process with sodium borohydride. The AgPt nanoparticles were prosperous in catalytic degrading methyl orange following a first order kinetic model.

在该项目中，使用番红花制备了银铂（AgPt）纳米颗粒L.植物乙醇提取物。AgPt纳米颗粒通过应用各种方法进行表征，如紫外可见光谱和红外光谱，电子显微镜和X射线衍射分析。形态结构表明，AgPt纳米颗粒为直径约36.0nm的球形颗粒。FTIR光谱显示了通过植物成分对AgPt纳米颗粒的有效稳定作用。Ag和AgPt纳米颗粒具有多酚含量，低于类黄酮和原花青素含量。与Ag纳米颗粒和抗坏血酸相比，AgPt纳米颗粒具有最高的抗氧化性能。结果表明，AgPt纳米颗粒具有很高的抗氧化性能。此外，AgPt纳米颗粒对病原微生物和MCF-7乳腺癌细胞系具有显着的抗微生物和细胞毒活性。环境化学分析表明，甲基硼可以通过硼氢化钠的催化降解过程从水中降解。按照一阶动力学模型，AgPt纳米颗粒在催化降解甲基橙方面很成功。
