This is a report on photo-irradiated extracellular synthesis of silver nanoparticles using the aqueous extract of edible oyster mushroom (Pleurotus florida) as a reducing agent. The appearance, size, and shape of the silver nanoparticles are understood by UV-visible spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and atomic force microscopy. The X-ray diffraction studies, energy dispersive X-ray analysis indicate that particles are crystalline in nature. Fourier transform infrared spectroscopy analysis revealed that the nanoparticles are covered with biomoieties on their surface. As can be seen from our studies, the biofunctionalized silver nanoparticles thus produced have shown admirable antimicrobial effects, and the synthetic procedure involved is eco-friendly and simple, and hence high range production of the same can be considered for using them in many pharmaceutical applications.
这是一份关于利用食用牡蛎菇（佛罗里达牡蛎菇）的水提物作为还原剂在光照条件下进行银纳米粒子的体外合成的报告。通过紫外-可见光谱、场发射扫描电子显微镜、透射电子显微镜和原子力显微镜可以了解银纳米粒子的外观、尺寸和形状。X 射线衍射研究和能谱分析表明，这些粒子具有晶态特性。傅里叶变换红外光谱分析表明，纳米粒子表面覆盖有生物分子。从我们的研究中可以看出，所制备的生物功能化银纳米粒子具有令人瞩目的抗菌效果，而且所涉及的合成过程环保且简单，因此可以考虑大规模生产这种银纳米粒子，将其应用于许多药物制剂中。
