This study used a simple solution evaporation approach to make a bioinorganic titanium dioxide (Bi-TiO) photocatalyst for dye contaminant degradation. A variety of techniques, including -ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) coupled with energy dispersive -ray analysis (EDAX), and differential reflectance spectroscopy, had been employed to classify the structural and optical properties of the prepared bioinorganic photocatalyst (UV-DRS). Using simulated solar irradiation, the photocatalytic activity of the produced Bi-TiO nanoparticles was examined by detecting the degradation of a solution of methylene blue (MB) as a model dye molecule. The developed Bi-TiO photocatalyst demonstrates superior photocatalytic action than commercially available powder TiO, according to photo-degradation experiments. E. and S. bacterial strains were employed to assess the antibacterial activity of Bi-TiO nanoparticles. The most active molecules that gain antibacterial activity were examined in isolated or extracted components from the tulsi plant. The chosen compounds were docked with thymidylate kinase (TMPK), a potential therapeutic goal for the preparation of novel antibacterial drugs with the PDB ID of 4QGG. Five compounds, namely rosmarinic acid, vicenin-2, orientin, vitexin, and isoorientin, out of the 27 chosen compounds, showed a higher docking score and may aid in boosting antibacterial activity. The synthesized Bi-TiO nanoparticles produced antibacterial activity that was effective against Gram-positive bacteria. The nanomaterials that have been synthesized have a lot of potential in wastewater treatment and biomedical management technologies.
本研究采用简单的溶液蒸发法制备了一种用于染料污染物降解的生物无机二氧化钛(Bi-TiO)光催化剂。采用了多种技术,包括X射线衍射(XRD)、傅里叶变换红外(FT-IR)光谱、扫描电子显微镜(SEM)结合能量色散X射线分析(EDAX)以及漫反射光谱(UV-DRS),对制备的生物无机光催化剂的结构和光学性质进行了表征。利用模拟太阳辐射,通过检测作为模型染料分子的亚甲基蓝(MB)溶液的降解情况,考察了所制备的Bi-TiO纳米颗粒的光催化活性。根据光降解实验,所开发的Bi-TiO光催化剂表现出比市售粉末TiO更好的光催化作用。采用大肠杆菌和金黄色葡萄球菌菌株评估Bi-TiO纳米颗粒的抗菌活性。对从罗勒植物中分离或提取的成分中具有抗菌活性的最活跃分子进行了研究。将所选化合物与胸苷酸激酶(TMPK)进行对接,TMPK是制备新型抗菌药物的潜在治疗靶点,其PDB ID为4QGG。在所选的27种化合物中,迷迭香酸、异荭草苷、木犀草素、牡荆素和异木犀草素这5种化合物显示出较高的对接分数,可能有助于增强抗菌活性。合成的Bi-TiO纳米颗粒产生了对革兰氏阳性菌有效的抗菌活性。所合成的纳米材料在废水处理和生物医学管理技术方面具有很大的潜力。
