Preparation, Characterization and Antibacterial Activity of Malva Sylvestris L. Seed Extract Containing Novel Electrospun PVA Nanofibers

Abstract

Highlights• Novel PVA nanofibers containing Malva Sylvestris L. seed extract was fabricated.• Electrospinning technique was used to produce nanofibers.• Nanofiber diameters were 181.3 -244.3 nm.• Nanofibers are expected to be beneficial for medical applications.

Removal of lead from aqueous solution using electrospun nanofibers: preparation, characterization, adsorption isotherm, and kinetic study

“…Electrospinning was performed with PVA and PVA/MSs biocomposites (10/1, 10/2, and 10/4 wt%). 41 Biocomposites were prepared by mixing the PVA (10% by weight) solution, and an optimum polymer solution, with the extract. The extract concentration to be added to the biocomposite was determined as to the literature.…”

“…10 wt% PVA solution was selected as an optimum PVA solution and it was used in later studies. 41 The 10% (wt) PVA solution was prepared by dissolving PVA in water under stirring for 3 h at 85 °C to form a homogeneous solution in the ultrasonic bath and then it was continued to stir at room temperature for 24 hours.…”

“…This procedure was previously reported by our research group. 41 Biocomposite samples were collected on aluminium foil and prepared for characterization. PVA (10%): MSs (2%) as the optimum biocomposite nanofiber was elected.…”

Nanofibers produced from medicinal and aromatic plant extracts by electrospinning method

“…PLANT-BASED NANOFIBERS Many herbal extracts have been effectively used in nanofiber electrospinning technology. Some of the plants that have been used include Zataria multiflora [21,22], Salvia hispanica L. [19], Malva syvestris [26,54], Laurus nobilis [32], Rosmarinus officinalis [32], garlic [23,33], Bergamot [16], Melissa officinalis [27], Inula graveolens (L.) [28], Allium cepa L. [34,35], Juniperus chinensis [26], Panax Ginseng [36], Allium ursinum L. [37], Rhodomyrtus tomentosa [24], Opuntia ficus-indica [38], Garcinia mangostana L. [39], Lawsonia Inermis [40,41], Cleome droserifolia [42], Tridax Procumbens [43], Moringa oleifera [44].…”

“…The average diameters of the nanofibers ranged from 180 to 244 nm. They also showed antibacterial activity against a variety of microbes, including gram-negative such as P. aeruginosa and E. coli [54].…”
