Size Control Technology of Silver Nanoparticles Using Electron Beam Irradiation

Electron Beam-Supported Fabrication of Biocompatible Silver/iota-Carrageenan for Wound Healing Application

“…Because each repeating unit of the disaccharide contains two sulfate groups, it has anionic characteristics in aqueous solutions. Furthermore, the polysaccharide’s hemiacetal, sulfate, hydroxyl, and carbonyl groups can operate as Ag­(I) nucleating sites via electrostatic and hydrogen interactions . Furthermore, intermolecular and intramolecular hydrogen bonding in polyhydroxylated carrageenan macromolecules result in the formation of networks inside the polymer chains that act as templates for the formation of nanoparticles. , In the course of this procedure, H • , OH • , OOH • , and O • , as well as hydrated electrons (e aq ) are produced by the dissociation of water molecules (eq ).…”

“…Microscopic Morphology of Biofilms Formed by S. aureus and E. coli. Using a previously published method, 26,27 the biofilm structure and phenotypic modifications of S. aureus and E. coli on nylon membranes were investigated. In brief, a sterile nylon barrier (0.45 μm) of 0.7 × 0.7 cm 2 was added in 96-well plates in which S. aureus and E. coli were grown in LB and further treated by ι-carra@ AgNPs (0−50 μg/mL), 37 °C, for 24 h. Formaldehyde and glutaraldehyde solution at a ratio of 1:1 was used to fix S. aureus and E. coli cells that had attached to nylon membranes.…”

Fabrication and durable antibacterial properties of electrospun chitosan nanofibers with silver nanoparticles

“…A c c e p t e d M a n u s c r i p t nm, respectively. These results were ascribed to the aggregation of AgNPs, which may be caused by constantly attack of the Ag atoms by hydrated electrons and hydrogen atoms generated during the e-beam process at relatively high dose and high concentration [21,24]. To further explore the distribution of AgNPs on the NFs, metal mapping image and EDX of hybrid NFs was taken (Fig.…”

“…One role of EBI treatment was to decrease the molecular weight of CS for dissolving in 1% acetic acid aqueous solution [8], the other role was large scale production of AgNPs according to the procedure described by Kang et al [24].…”

“…Furthermore, EBI treatment is possible to control the size and suppress the agglomeration of as-obtained AgNPs, which affect the property of nanoparticles [21,23]. Generally, radiation-induced reduction performs as follows [24], 1) Water radiolysis:…”
