Electrospinning: la era de las nanofibras

The technique of electrospinning or electrospinning has been widely studied in recent years thanks to the possibility of creating fibers on a micro and nanometric scale for a wide variety of biomedical applications. This technique provides the developed elements with various characteristics such as: large surface area per unit. of area, porosity and a series of mechanical properties, being attractive at a biotechnological level. The technique is versatile and easy to assemble, which has allowed the processing of a wide variety of polymers, integrating other types of materials in recent years, however, during the development of the process there are a series of variables that influence the characteristics of the elements obtained , either because they are linked to the characteristics of the base material or because their performance is related to other parameters within the process. The objective of this review is to clarify the influence and interrelation of some variables in the process as well as to reveal the most important advances in the development of the technique and in relation to drug release for medical applications.
