    Medicated skin care products are available in various forms; ranging from lotions and creams to bandages and membranes. In this study, anti-bacterial particulate laden fibrous membranes were prepared via electrospraying of tetracycline hydrochloride (TE-HCL) loaded poly(ε-caprolactone) (PCL) particles alongside electrospinning of thermoplastic polyurethane (TPU) fibers, through which both mechanical and biological aspects of a complete membrane system can be achieved. Random (R) and ordered (P and V) patterns of TPU fibrous membranes (FMs) were afforded using a rotating collector. Water contact angle and bacterial inhibition zone tests were performed to assess suitability of the system specifically for wound care. Stress-strain and in-vitro drug release tests were performed to assess suitability of newly developed systems specifically for hybrid membranes (HMs). The highest tensile strength (32.1 ± 4.9 MPa) with elasticity (104.2 ± 6.0 %) and the most sustained release rate indicate HMs (P) are potentially suitable materials for wound care applications.
