One of the most relevant techniques to fabricate polymer nanofibers with unique core-sheath or hollow structures (micro/nanocapsules, hollow spheres, hollow fibers and coaxial fibers) is the recently discovered Coaxial Electrospinning and Electrospray technique. The development of this method of encapsulation could be very relevant in food items, pharmaceuticals, textile industry, controlled drug delivery, catalysis, bioengineering, […]
