Electrospinning is a method utilized to produce nano-scale fibers for tissue engineering applications. A variety of cells are attracted by nano scale surfaces and structures probably due to the similarity of their natural environment scale. In this study, diclofenac sodium (DS) releasing nanofibers were manufactured via electrospinning process. Poly(95 ε-capro/5 D,L-lactide) was dissolved into acetic acid to form a 20% w/v solution. 2% w/w of DS was then added into the polymer solution and stirred homogenously. About 1 g of polymer/drug solution was spun onto the collector under electrostatic conditions. The distance between needle tip and sample collector was arranged to 10 cm and applied electric field was 2 kV/cm. Release rate of DS was measured by using UV/VIS spectrophotometer. Resulted highly porous nanofiber scaffold was about 2 mm thick and the diameter of nanofibers was approximately 130 nm. Structure included in also spheres with approximately diameter of 3.30 μm. About 45% of DS was released during the first 24 hours and after that the release decreased to almost zero value. After 35 days release rate increased. This study revealed that manufacturing of highly porous DS releasing nanoscaffold by electrospinning process is feasible. Having fast DS release rate nanofibrous scaffold made of poly(95 ε-capro/5 D,L-lactide)can be of benefit for applications where immediate control of tissue reaction is needed.
