“…The greatest inhibition zone was created by Bi-TiO 2 nanoparticle over E. coli (7.9 mm) bacterium when the inhibition zone of plates was measured. A sum of three tests is carried out and the action of synthesized Bi-TiO 2 generated hydroxyl groups and reactive oxygen species (ROS), which are capable of melting the cell wall because phospholipid peroxidation of bacteria leads to death [ 41 , 42 ], is the mechanism of this well-developed antibacterial activity. In this paper, Bi-TiO2nanoparticles are shown to be an effective antimicrobial medicine that can pave the way for the development of novel antimicrobial pharmaceuticals and agents.…”

This study used a simple solution evaporation approach to make a bioinorganic titanium dioxide (Bi-TiO2) photocatalyst for dye contaminant degradation. A variety of techniques, including X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) coupled with energy dispersive X-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-TiO2 nanoparticles was examined by detecting the degradation of a solution of methylene blue (MB) as a model dye molecule. The developed Bi-TiO2 photocatalyst demonstrates superior photocatalytic action than commercially available powder TiO2, according to photo-degradation experiments. E.coli and S.aureus bacterial strains were employed to assess the antibacterial activity of Bi-TiO2 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-TiO2 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.

“…It was been demonstrated that the interaction between GO and plasmid DNA inhibits the amplification and transformation of aphA genes. Moreover, the inhibition increases with the decreasing size of the GO [111,112]. The heterostructures created by combining g-C 3 N 4 with graphene oxide (GO/g-C 3 N 4 ) could kill 97.9% of E. coli after 120 min visible light irradiation at the concentration of 100 µg/mL (Table 1).…”

“…For instance, bacteriophage MS2, a widely used surrogate for waterborne pathogenic viruses due to their similar size, structure, and surface properties, was selected as a model virus in the study by Zhang et al [74]. Viruses and fungi are more resistant than bacteria to conventional disinfection methods [111], and the results of bacterial disinfection cannot be translated to viral disinfection. The mechanism of the photocatalytic inactivation of viruses is still largely unknown [67].…”

“…where P is the nominal power of the light source (kW), t is the irradiation time (minutes), V is the volume solution (L), C 0 is the E. coli initial concentration (UFC/mL), and C f is the E. coli final concentration. Assuming 10 min as the treatment time, we compared the EE/O values of two photocatalysts, ZnO/TiO 2 [1] and Cu/ TiO 2 [111].…”

Antimicrobial Effectiveness of Innovative Photocatalysts: A Review

et al. 2022

Waterborne pathogens represent one of the most widespread environmental concerns. Conventional disinfection methods, including chlorination and UV, pose several operational and environmental problems; namely, formation of potentially hazardous disinfection by-products (DBPs) and high energy consumption. Therefore, there is high demand for effective, low-cost disinfection treatments. Among advanced oxidation processes, the photocatalytic process, a form of green technology, is becoming increasingly attractive. A systematic review was carried out on the synthesis, characterization, toxicity, and antimicrobial performance of innovative engineered photocatalysts. In recent decades, various engineered photocatalysts have been developed to overcome the limits of conventional photocatalysts using different synthesis methods, and these are discussed together with the main parameters influencing the process behaviors. The potential environmental risks of engineered photocatalysts are also addressed, considering the toxicity effects presented in the literature.

“…There is increasing concern about the release of pharmaceuticals as they have been detected in various water matrices at low concentrations (μg L − 1 or ng L − 1 ) [1,2]. Furthermore, the release of antibiotics can contribute to the rise in antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs), posing a global threat to human health [3]. Due to the continuous presence of viruses in wastewater and the recent COVID-19 (SARS-CoV-2) pandemic there is increasing concern about the transmission of viral pathogens [4,5].…”
