Rapid and efficient antibacterial activity of Molybdenum-Tungsten oxide from nn heterojunctions and localized surface plasmon resonance

摘要: With a surge in bacteria encroaching on our daily life, exacerbated antimicrobial resistance toward antibiotics, and sagacious short- and long-term responses of bacteria toward novel antibacterial nanoparticles, the need for developing rapid and effective antibacterial agents is increasing. Herein, Mo0.55W0.45O3–x samples are synthesized through a coprecipitation process, followed by annealing at 450–600 °C. Mo0.55W0.45O3–x samples showed outstanding activity after 10 min of incubation against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) under the compact fluorescent lamp irradiation; the activities were 98.948 ± 1.890 and 98.413 ± 1.080% for S. aureus and E. coli, respectively. The role of each reactive oxygen species (ROS) in suppressing bacteria was studied. The strikingly fast antibacterial rate was discovered with respect to semiconducting features of Mo0.55W0.45O3–x samples …
