On-Paper Synthesis of Silver Nanoparticles for Antibacterial Applications

One-step flame synthesis of silver nanoparticles for roll-to-roll production of antibacterial paper

“…Hence, it has been difficult to produce antibacterial paper with silver nanoparticles until recently. The challenge of producing paper with silver nanoparticles was overcome using chemical reduction technique [22,23]. Techniques that have successfully incorporated silver nanoparticles on paper substrates typically expose the whole paper matrix for chemical modification.…”

Silver Nanoparticle Surface Functionalized Alumina Filters for Disinfection of Potable Water

“…The activity of silver differs depending on its form: bulk, ion or nanoparticles. Bactericidal activity is size dependent [7,8] and those under 10 nm are reported to be more toxic to microorganisms [3,9,10]. While the antimicrobial effect of silver is vastly known, the mechanisms of action are only partially understood.…”

“…Some postulates are that the interaction of Ag + with thiol groups in membrane proteins inactivates respiratory enzymes and produces reactive oxygen species [10]. It has been proven that the ion Ag + stops DNA replication and affects the structure and permeability of the cellular membrane damaging cellular respiration [7,8,10]. Morones and colleagues [9] suggest as mechanisms: (1) adhesion of nAg on cell surface, modifying membrane properties and increasing permeability, (2) cell penetration of nAg damaging DNA and (3) dissolution of nAg causing toxic ion Ag + to be released into the cell.…”

Silver Alginate Hydrogel Micro- and Nanocontainers for Theranostics: Synthesis, Encapsulation, Remote Release, and Detection

“…In this regard, their modification of delivery containers with silver nanoparticles makes possible to change optical properties of microcontainers, − to accomplish the detection of substances by using surface enhanced Raman scattering (SERS), − to enhance mechanical characteristics of the material, and to increase its sensitivity to ultrasonic exposure by controlling the density of the shell . Due to its antiseptic properties, silver nanoparticles possess antimicrobial − and antibacterial properties, − and its incorporation into microcapsules opens prospects for their application in medicine.…”
