Biosynthetic procedure is the best alternative to the preparation of nonmaterials as the challenges faced by the scientist from the last few decades. Present research reports cost-effective, inexpensive eco-friendly synthesis of titanium dioxide nanoparticles using a methanolic extract of fruits peel agro-waste. X-ray diffraction spectrum of identified TiO₂NPs found noncrystalline in nature. Fourier transform infrared showed O–H, C = O, C–O, and C–H functional groups present in the fruit peel involved in the biosynthesis of TiO₂NPs. The prominent peak at 1708, 1720 and 1700 cm⁻¹ observed in the spectrum attributed to O–Ti–O stretching in Plum, Kiwi and Peach mediated TiO₂NPs. The SEM images of all three TiO₂NPs revealed cylindrical in shape. The size of TiO₂NPs synthesized from Plum, Kiwi and Peach were found to be 47.1 and 63.2, 54.1 and 85.1 and 200 nm, respectively. All the TiO₂NPs exhibited size- and dose-dependent antibacterial and antioxidant activities.

生物合成方法是非材料制备的最佳替代方法，因为过去几十年来科学家一直面临着挑战。目前的研究报道了使用果皮农业废料的甲醇提取物，经济高效，廉价的环保合成二氧化钛纳米颗粒。发现的TiO ₂ NP的X射线衍射光谱本质上是非晶态的。傅里叶变换红外光谱显示果皮中存在OH，C = O，C–O和C–H官能团，这些官能团与TiO ₂ NP的生物合成有关。在光谱中观察到的突出峰出现在1708、1720和1700 cm ^-1处，归因于李子，猕猴桃和桃子介导的TiO ₂ NP中的O–Ti–O拉伸。所有三种TiO ₂的SEM图像NP呈圆柱形。由李子，猕猴桃和桃子合成的TiO ₂ NP的大小分别为47.1和63.2、54.1和85.1和200nm。所有的TiO ₂ NPs都显示出大小和剂量依赖性的抗菌和抗氧化活性。
