Fabrication of antibacterial polyvinylalcohol nanocomposite mats with soluble starch coated silver nanoparticles

Optimization of the electrospinning process variables for gelatin/silver nanoparticles/bioactive glass nanocomposites for bone tissue engineering

“…Using the Scherrer equation, the mean Ag‐NPs crystallite size in the nanofiber structure was estimated using the full widths at the half‐maximum of the characteristic peaks (111), (200), and (220) . As a result, the average silver size in the nanofiber membrane was calculated approximately 19.3 ± 1.3 nm, which showed that the size of the Ag‐NPs in the nanofiber membrane was the similar to the Ag‐NPs average size of the 19 ± 6 nm obtained in our previous study …”

“…In the XRD pattern of the electrospun membrane, the diffraction peak at around 2Ɵ = 20° with an expanded band is shown due to the amorphous structure of the gelatin. The X‐ray diffraction of the Gt‐Ag‐BG sample shows three of the Bragg reflection peaks at 38.8°, 44.9°, and 65.1° separately from the gelatin peak, corresponding to the (111), (200), (220) planes of the face centered cubic structured metallic silver . Using the Scherrer equation, the mean Ag‐NPs crystallite size in the nanofiber structure was estimated using the full widths at the half‐maximum of the characteristic peaks (111), (200), and (220) .…”

“…For the synthesis of silver nanoparticles, Bosch microwave oven (model: HMT882H) was used. The desired solution mixture was reacted in that domestic microwave oven operated at 180 W and a frequency of 2450 MHz, for 1h to obtain silver nanoparticle (Ag‐NPs) solution …”

Poly(vinyl alcohol) triggers Au nanoparticles formation for near‐infrared radiation‐responsive gels and nanofibers

“…In most cases, preformed nanoparticles (e.g., quantum dots, metal particles, magnetite, and other metal oxides), nanofibers (e.g., glass fibers, carbon fibers, nanocellulose), or nanosheets (e.g., graphene oxide, GO) are mixed with PVA before processing of the device. For example, silver nanoparticles have been incorporated to PVA nanofibers to obtain antimicrobial wound dressings . As an alternative, silver nanostructures can be generated in the presence of PVA by means of electron‐beam lithography for plasmonic circuitry .…”

“…For example, silver nanoparticles have been incorporated to PVA nanofibers to obtain antimicrobial wound dressings. 12 As an alternative, silver nanostructures can be generated in the presence of PVA by means of electronbeam lithography for plasmonic circuitry. 13 PVA performs as stabilizer of gold nanoparticles (Au NPs) when prepared by reduction with sodium borohydride; relevantly, the Au NPs size can be tuned by changing the polymer/metal ratio.…”
