A corrigendum was issued for the article "Silver nanoparticles: synthesis, properties, toxicology, applications and perspectives" published in Adv. Nat. Sci: Nanosci. Nanotechnol. 4 (2013) 033001. The correction addresses an error in Table 1, where the reference for AgNO3/thermal decomposition was incorrectly cited as [13] and should be [20]. The corrected table is provided. The article reviews the synthesis, antimicrobial effects, toxicology, and applications of silver nanoparticles (Ag-NPs) against various pathogens, including bacteria, fungi, and viruses. It discusses the potential of Ag-NPs in environmental disinfection and their future prospects in treating and preventing emerging infections. The review covers seven sections, including synthesis methods, antimicrobial effects, toxicology, environmental applications, and future perspectives. The synthesis of Ag-NPs is discussed through chemical, physical, photochemical, and biological methods. The antimicrobial effects of Ag-NPs are analyzed against bacteria, fungi, and viruses, with mechanisms of action discussed. The article also explores the toxicology of Ag-NPs to humans and the environment, and their current applications in environmental treatments. The review concludes with future prospects for Ag-NPs in environmental disinfection and their potential as antiviral agents. The article highlights the importance of Ag-NPs in combating infectious diseases and their potential in various applications, including air and water disinfection.A corrigendum was issued for the article "Silver nanoparticles: synthesis, properties, toxicology, applications and perspectives" published in Adv.
