Ag nanoparticle–ZnO nanowire hybrid nanostructures as enhanced and robust antimicrobial textiles via a green chemical approach

Abstract

A new approach for fabrication of a long-term and recoverable antimicrobial nanostructure/textile hybrid without increasing the antimicrobial resistance is demonstrated. Using in situ synthesized Ag nanoparticles (NPs) anchored on ZnO nanowires (NWs) grown on textiles by a 'dip-in and light-irradiation' green chemical method, we obtained ZnONW@AgNP nanocomposites with small-size and uniform Ag NPs, which have shown superior performance for antibacterial applications. These new Ag/ZnO/textile antimicrobial composites can be used for wound dressings and medical textiles for topical and prophylactic antibacterial treatments, point-of-use water treatment to improve the cleanliness of water and antimicrobial air filters to prevent bioaerosols accumulating in ventilation, heating, and air-conditioning systems.

Arginine-assisted immobilization of silver nanoparticles on ZnO nanorods: an enhanced and reusable antibacterial substrate without human cell cytotoxicity

“…10,11 Silver nanoparticles immobilized on various inorganic and organic substrates such as SiO 2 , Fe 2 O 3 , zinc oxide, and graphene have demonstrated an enhanced antibacterial performance over long term use. 7,[12][13][14] Other than metallic silver, zinc oxide (ZnO) has also been widely reported to inhibit and inactivate microbial growth at the nanoscale. Being relatively cheaper, non-toxic, and biocompatible, ZnO is an important ingredient for various cosmetic products and antibacterial lotions and is commonly used as a drug carrier and filler in dental materials.…”

“…16,17 To date, a variety of methods have been explored for the incorporation of Ag on to ZnO support material through doping, ultrasonication, the solvothermal method, pulsed layer deposition, irradiation assisted anchoring or in situ synthesis of AgNPs. 13,[18][19][20][21] From the point of view of immobilization, silver nanoparticles can readily self-assemble on ZnO templates as they provide both anchoring sites for the metal ions to bind and nucleation sites for their subsequent growth. However, in the absence of any binder/linker, it is extremely difficult to control the dispersivity, stability and loading of silver nanoparticles over ZnO surfaces.…”

Assembly of silver nanoparticles on nanowires into ordered nanostructures with femtosecond laser radiation

“…Of the many possible nanostructures, those consisting of nanoparticle-nanowire configurations have received special attention due to high photon-electron coupling efficiency [4,5], leading to potential applications as optical modulators [6]. Nanoparticlesnanowire structures can be produced in various ways including via chemical mixing reactions [7], electron beam lithography [8], and mechanical buckling [6]. However, these methods are often limited by toxicity, high cost, and low efficiency.…”

Photoactivated Trifunctional Platinum Nanobiotics for Precise Synergism of Multiple Antibacterial Modes

“…Some inorganic and organic nanomaterials have been synthesized to mimic natural enzymes and antibodies to eliminate bacteria and debride infections . Furthermore, several metal‐oxide‐based nanospheres treated with surface modification or hollow NPs are regarded as carriers of antimicrobial drug delivery systems . However, complicated synthetic methods as well as low drug loading and release rate remain some of the challenges in application at a large scale.…”
