The study reports on synthesis of aqueous extract mediated gold and silver nanoparticles of M. biflora (MBAuNPs and MBAgNPs) via hydrated chloroauric acid and silver nitrate salts. The nanoparticles (NPs) were produced in 1:15 (MBAuNPs) and 1:6 (MBAgNPs) ratios under sunlight displaying localized surface plasmon resonance (LSPR) peaks at 541 and 431 nm, respectively. The sizes characterized by transmission electron, scanning electron, and atomic force microscopic (SEM, TEM, AFM) techniques were respectively 26.73 nm and 53.81 nm. The subject NPs demonstrated application in the degradation of methylene blue, Congo red, Rhodamine B, methyl orange, ortho-nitrophenol, and para-nitrophenol ranging from 65 to 86%. For detection of levofloxacin, amoxicillin, and azithromycin antibiotics, the MBAuNPs and MBAgNPs exhibited efficiency in real water and biological (blood plasma and urine) samples. Conclusively, the MBAuNPs and MBAgNPs applications for dyes degradation and antibiotics detection was found as simple and cost-effective analytical method.

该研究报告了通过水合氯金酸和硝酸银盐合成水提取物介导的双花金银纳米颗粒（MBAuNP 和 MBAgNP）。纳米粒子 (NP) 在阳光下以 1:15 (MBAuNPs) 和 1:6 (MBAgNPs) 的比例生产，分别在 541 和 431 nm 处显示局部表面等离子共振 (LSPR) 峰。通过透射电子、扫描电子和原子力显微镜（SEM、TEM、AFM）技术表征的尺寸分别为26.73 nm和53.81 nm。主题 NP 被证明可用于降解亚甲基蓝、刚果红、罗丹明 B、甲基橙、邻硝基苯酚和对硝基苯酚，降解率范围为 65% 至 86%。对于左氧氟沙星、阿莫西林和阿奇霉素抗生素的检测，MBAuNP 和 MBAgNP 在实际水和生物（血浆和尿液）样品中表现出效率。最后，MBAuNP 和 MBAgNP 在染料降解和抗生素检测中的应用被认为是简单且经济高效的分析方法。
