“…Many electrospun nanofibers made from plant extracts blended with either natural or synthetic polymers have been used for numerous biomedical purposes so far [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. One such plant is Tridax procumbentsis , which has been successfully transferred into nanofibrous mats and blended with PVA by Ganesan et al They also examined the antimicrobial activity of these nanofibrous mats and found that the natural potential of plants can be effectively shifted to a structure that can be used for medicinal treatments [ 22 ]. Likely, Avci et al prepared antibacterial PVA and poly(ethylene oxide) nanofibers incorporating henna leaf extracts [ 23 ], and a wound dressing technique having an antibacterial activity was successfully prepared by PVA loaded with soursop leaf extract by Aruana and his group [ 24 ].…”

Coptis chinensis (CC) is used in conventional Chinese medicine. The main active components of CC are isoquinoline alkaloids, including berberine, coptisine, palmatine, and magnoflorine; all these are known to have several pharmacological properties. Poly(vinyl alcohol) (PVA) is a well-known synthetic biocompatible polymer suitable for a range of pharmaceutical uses; it can be used as a matrix for the incorporation of functional materials and has a wide range of applications in the cosmetics, food, pharmaceutical, and packaging industries. In this study, PVA-based electrospun nanofibers containing CC extract were successfully fabricated. Furthermore, the effects of different CC extract contents on the morphologies, and antimicrobial and antifungal properties of PVA/CC extract nanofibers were investigated. Morphological changes were observed using different molecular weights of PVA. For characterization, field-emission scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared analysis were performed. The effectiveness of these nanofibers has been demonstrated by evaluating the thermal stability against Staphylococcus aureus, antimicrobial activity against Staphylococcus aureus and Staphylococcus epidermidis, and the antifungal activity against the fungi Aureobasidium pullulans and Penicillium pinophilum. The PVA/CC extract nanofibers were found to have excellent antibacterial and antifungal activity and thermal stability; hence, their use in medicinal sectors is highly recommended.

“…and bactericidal efficiency against S. aureus [ 110 ]. Similarly, the methanolic extracts of Tridax procumbens leaves [ 111 ] and the aqueous extracts of Coptis chinensis [ 112 ] were employed to prepare nanofibrous mats with antimicrobial activity. PVA/ Tridax procumbens nanofibers showed an outstanding zone of inhibitions and improved resistivity power against S. aureus and E. coli , whereas PVA/ Coptis chinensis nanofibers, evaluated against different Gram-positive bacteria, displayed the highest antibacterial activity against S. epidermidis .…”

Site-Specific release of active molecules with antimicrobial activity spurred the interest in the development of innovative polymeric nanocarriers. In the preparation of polymeric devices, nanotechnologies usually overcome the inconvenience frequently related to other synthetic strategies. High performing nanocarriers were synthesized using a wide range of starting polymer structures, with tailored features and great chemical versatility. Over the last decade, many antimicrobial substances originating from plants, herbs, and agro-food waste by-products were deeply investigated, significantly catching the interest of the scientific community. In this review, the most innovative strategies to synthesize nanodevices able to release antimicrobial natural extracts were discussed. In this regard, the properties and structure of the starting polymers, either synthetic or natural, as well as the antimicrobial activity of the biomolecules were deeply investigated, outlining the right combination able to inhibit pathogens in specific biological compartments.

Nanofibers are a type of nanostructures, which due to their unique properties can be used in wound dressing, and electrospinning is a good way to produce them. The benefits of wound dressings made of electrospun nanofibers include a large surface area to volume ratio, high absorption of secretions from the wound, and high air permeability, mimicking the morphology of extracellular matrix (ECM) of the damaged tissue and the possibility of the gradual release of the drug agents loaded on nanofibers. Because of the adaptability of plants to the body, low side effects and the prevalence of antibiotic resistance, interest in using plants is increasing. Combining nanofibers with plants is a way to integrate the physical properties of the structure of nanofibers and the chemical and antibacterial properties of the plants. In recent years, many plants in the forms of extracts, essential oils, and pure active ingredients have been used in the electrospininng and production of nanofibercontaining plants; some of the plants may be a good choice for wound dressings made of electrospun nanofibers.
