Bactericidal Action and Industrial Dye Degradation of Graphene Oxide and Polyacrylic Acid-Doped SnO2Quantum Dots:In SilicoMolecular Docking Study

“…The morphologies of SnO 2 and doped SnO 2 were examined by transmission electron microscopy (TEM) analysis (Figure a–d). TEM micrographs confirmed the formation of agglomerated QDs of SnO 2 ; this agglomeration could be due to hydrogen bonding of DI water during the synthesizing process (Figure a). Upon doping of the capping agent (PAA), a higher degree of agglomerations was observed with a reduction in the particle size confirmed through image J software (Figure b).…”

“…Catalytic activity is dependent on the catalyst concentration because it enhances dye degradation by lowering the activation energy of a chemical reaction. In general, larger surface area catalysts have demonstrated a higher catalytic performance because they contain more active sites and the pH of the solution has a significant impact on the degradation efficiency . Due to the possibility of a large redox potential difference between the electron donors and acceptor species, which can inhibit electron transfer, the electron-transfer step plays a dynamic role in dye degradation .…”

Nanomaterials Based Multifunctional Bioactivities of V2O5 and Mesoporous Carbon@V2O5 Composite: Preparation and Characterization

“…Therefore, a substantial effort has been made in the current case to examine biomedical applications like antioxidant, antimicrobial, anticancer, and drug delivery from such intriguing elements. V 2 O 5 is prepared using a variety of chemical as well as physical techniques, including hydrothermal process, 21 coprecipitation, 22 sol−gel synthesis, 23 and electrochemical deposition (Table 1). 24 Among the different techniques, the sol−gel method is an easy, affordable, efficient, and environmentally friendly technique.…”

Efficient Dye Degradation and Antibacterial Activity of Carbon Dots/Chitosan-Doped La2O3 Nanorods: In Silico Molecular Docking Analysis

“…Furthermore, poisonous microbes present in water as bacteria, fungi, algae, plankton, and amoebas cause several waterborne diseases . Drinking polluted water causes numerous diseases, namely, diarrhea, tooth and bone cancer, hepatitis, typhoid, dysentery, and aquatic illness, and even death . Multiple chemical, biological, and physical solutions have been developed to tackle this environmental concern.…”
