The antimicrobial drug resistance is increasing with the passage of time due to wide and improper use of broad spectrum drugs and the demand of the new drug increases day by day. The present study was planned to encounter this problem by synthesizing titanium dioxide nanoparticles (TiO2 NPs) by an eco-friendly route using Cannabis sativa leaves extract. The synthesized TiO2 NPs were calcined at 100, 300, 600, and 900°C in a muffle furnace. The crystallographic parameters were studied by X-ray diffraction and the phase transition occurred above 600°C. The surface morphology of the synthesized samples was studied by transmission electron microscopy (TEM), and scanning electron microscopy (SEM) and the particle size was measured through the ImageJ software. The elemental composition and purity of all the samples were studied by performing energy dispersive X-ray (EDX). All the synthesized TiO2 NPs were tested for their antimicrobial effect against Gram-positive and Gram-negative bacteria using the agar well diffusion method. The activity was found higher against Gram-negative bacteria and compared to Gram-positive bacteria.

生物合成二氧化钛纳米粒子的结构和生物学研究:煅烧和表征

由于广谱药物的广泛使用和不当使用,抗菌药物的耐药性随着时间的推移而增加,对新药的需求日益增加。本研究计划通过使用大麻叶提取物通过环保途径合成二氧化钛纳米粒子 (TiO 2 NPs) 来解决这个问题。合成的TiO 2NPs 在马弗炉中在 100、300、600 和 900°C 下煅烧。通过 X 射线衍射研究结晶参数,相变发生在 600°C 以上。通过透射电子显微镜(TEM)和扫描电子显微镜(SEM)研究合成样品的表面形貌,并通过ImageJ软件测量粒径。通过进行能量色散 X 射线 (EDX) 研究所有样品的元素组成和纯度。使用琼脂井扩散法测试了所有合成的 TiO 2 NPs 对革兰氏阳性菌和革兰氏阴性菌的抗菌作用。与革兰氏阳性细菌相比,发现其对革兰氏阴性菌的活性更高。
