Aim: The aim of this study determined the feasibility of a handheld electrospinning device for the application of wound dressings. Methods: A porcine model was used to apply four polymer nanofibers dressings onto superficial partial thickness wounds and compared with a traditional paraffin tulle gras dressing. Using a handheld portable electrospinning device, the four polymer nanofibrous dressings were applied at a short distance from the wound. Donor sites were evaluated on day 2, 7, and 14 after removal of dressings. Tissue samples were taken for histological assessment. Results: There were no significant differences detected between the electrospun nanofibrous and paraffin tulle gras dressings. Positive characteristics of the electrospun nanofiber dressings included a non-touch technique, the ease of application, adherence and reduction in wound oedema and inflammation. Observed was no delayed wound healing or signs of infection in either of the electrospun nanofiber and traditional tulle gras dressings. Innovation: For application on partial thickness wounds, polymer electrospun nanofiber dressings provide superior surface topography with a non-touch, feasible, and safe method to promote moist wound healing. Therefore, the use of polymer nanofibrous dressings have implication for the reduction of wound infections, pain and trauma, number of dressing changes, scarring, and an added cost benefit. Conclusion: We have demonstrated that this portable handheld electrospinning device can be employed for different formulations and materials and customised according to the characteristics of the target wound at the various stages of wound healing.
