“…In general, the decrease in viscosity and surface tension improves the processability and decreases the average diameter of the fibers. In contrast, the decrease in electrical conductivity has the opposite effect . The results presented show two parameters favored with the addition of the active principle and an unfavorable one so that the final interaction favored the process as a whole.…”

“…The formation of nanofibers is mainly affected by three categories of parameters, namely process parameters (including applied voltage, solution feed rate, tip-to-collector distance, and collector speed), solution parameters (such as polymer solution concentration, polymer molecular weight, viscosity, surface tension, and conductivity), and environmental parameters (such as relative humidity and temperature). 4 Polymers are the main raw materials used in the manufacturing of electrospun nanofibers. They can be synthetic and/or natural; the choice of their nature is dependent on the desired application.…”

Electrospinning has stood out as a promising technique for producing innovative dressings. In this regard, this study aimed to evaluate the effect of crosslinking with maleic anhydride (MA) at 0, 15, and 30 wt % on the morphological, physicochemical, and thermal properties and storage stability of electrospun hyaluronic acid /polyvinyl alcohol membranes loaded with Plantago major extract. The crosslinking enhanced the manufacturing process of the membranes. It reduced the average diameter of crosslinked nanofibers with 30 wt % MA by about 20 nm and increased the maximum decomposition temperature by 12 °C compared to control samples. Furthermore, crosslinking prevented the phase separation of the blend, making the crosslinked membranes more homogeneous. The storage stability results indicated that lower relative humidities favored the maintenance of the physical structure of the membranes, and the sorption isotherms obtained by the experimental data were better fitted by the Guggenheim−Anderson−de Boer model. This investigation suggested a promising approach to designing new wound healing dressings.

“…This technique involves a simple method, and it has high versatility and low cost when compared to other techniques. It is based on the transformation of polymeric solutions in fibers on the nanometric or micrometric scale, and this is possible due to a high potential difference that is generated between the electrodes 17,18 that propel polymeric solutions towards a bulkhead.…”

Diabetes is one of the chronic diseases that most affect the world population, and it is estimated that in a few years it will progressively increase. It can appear at any stage of life, being Type I most common in childhood and Type II in adulthood, but both are related to hyperglycemia. Studies show that physical inactivity, obesity, and poor eating habits can influence the onset and/or worsening of Type II diabetes. Among the complications that diabetics may develop are amputations, these are caused due to the neuropathy that the diabetic develops and ends up losing sensitivity when injured. Consequently, the wounds often become infected ulcers and the tissue dies, leading the patient to undergo surgical procedures for tissue removal. To try to prevent wounds from becoming ulcers and/or to reduce the percentage of amputations, researchers have been using the electro‐spinning technique to form nanofibers. The fibers when electrospun have nanofiber morphology and one of the characteristics of these is the volume/area ratio in which positively increases the properties of the fibers. These are being widely used in tissue engineering as they have been shown to be effective in tissue regeneration. In addition, they prove to be promising in the biomedical area for modified drug release. Polymers such as poly (ε‐caprolactone), poly (lactic‐co‐glycolic acid), gum tragacanth, among others, are gaining ground in the scientific field to produce nanofibers incorporating some antioxidant, antimicrobial, and anti‐inflammatory agent. For treating diabetic wounds, preventing amputation processes and an improvement in the quality of life. The aim of this paper is to review the use of the electrospinning technique to aid the healing of diabetic wounds in the scientific literature.
