In situ preparation of silver nanoparticles on biocompatible methacrylated poly(vinyl alcohol) and cellulose based polymeric nanofibers

One-step synthesis of size-tunable Ag nanoparticles incorporated in electrospun PVA/cyclodextrin nanofibers

“…PVA can reduce the Ag + ions into Ag-NP due to the hydroxyl groups on the polymer backbone (Mahanta & Valiyaveettil, 2012) and also stabilize the Ag-NP by keeping them from aggregation. Yet, in order to control the size and ensure uniform dispersion of Ag-NP in PVA solution, we also used hydroxypropyl-beta-cyclodextrin (HP␤CD) as a supplementary reducing and stabilizing agent.…”

“…For example, silver nanoparticles (Ag-NP) have attracted considerable attention due to their unique optical, electronic, catalytic and antibacterial properties (Arvizo et al, 2012;Fouda, El-Aassar, & Al-Deyab, 2013;Rycenga et al, 2011). Several studies aimed at incorporation of Ag-NP within electrospun nanofibers which can enable production of functional nanofibrous composites by combining the unique properties of nanofibers with that of Ag-NP (Mahanta & Valiyaveettil, 2012;Nam et al, 2010;Shi et al, 2011;Xiao et al, 2012). Yet, the size control and uniform distribution of Ag-NP without aggregation in the polymeric nanofiber matrix is challenging, therefore, a number of different approaches were followed for obtaining electrospun polymer/Ag-NP composite nanofibers (Jin et al, 2007;Li et al, 2006;Patel, Li, Wang, Zhang, & Wei 2007;Xiao et al, 2012;Xu et al, 2006).…”

“…As well, "green" practices started to take their place in the electrospinning process by the use of natural and nonhazardous polymers (Mahanta & Valiyaveettil, 2012). Very recently, polymer/cyclodextrin/AgNO 3 mixtures were electrospun into polymer/Ag-NP composite nanofibers where the cyclodextrin was used as a stabilizing and reducing agent for the formation of Ag-NP in the polymer matrix (Chae, Kim, Yang, & Rhee, 2011;.…”

“…For example, one-step synthesis of Ag-NP incorporated in polyethylene oxide nanofibers (Saquing, Manasco, & Khan, 2009) or polyvinyl alcohol nanofibers (Mahanta & Valiyaveettil, 2012) was achieved where the polymer solution was used as both a reducing and protecting agent for Ag-NP and an electrospinning template. In other studies, polymer/Ag-NP composite nanofibers were produced in one-step by using the electrospinning solvent as a reducing agent and the electrospinning polymer matrix as a stabilizing/protective agent .…”

Existence, release, and antibacterial actions of silver nanoparticles on Ag–PIII TiO2 films with different nanotopographies

“…Thus, kinds of Ag nanoparticle-modified surfaces have been designed and prepared. [20][21][22] Plasma immersion ion implantation (PIII) technology has now been extensively utilized to modify the surfaces of a variety of biomedical materials/devices and found especially suitable for the ones with complex geometry shapes, due to the non-line-of-light feature. 23 The Ag-PIII method has been successfully developed for the purpose of enhancing the antibacterial ability of biomaterials and related devices to minimize infections.…”
