- Abstract:
Se presenta una breve descripción de la técnica electrohilado, alcance, aplicaciones actuales y una propuesta para el desarrollo de equipos que son relativamente sencillos de implementar, en instituciones educativas o centros de investigación. Recientemente la técnica llamada electrohilado es propuesta para el desarrollo armazones celulares, dispositivos que proporcionan a las células el apoyo necesario para su proliferación y el mantenimiento de sus funciones diferenciadas y las señales biológicas requeridas para la conservación de la expresión génica específica, además, definen la arquitectura del tejido. La técnica de electrospinning consiste en que una solución polimérica es forzada a través de una boquilla mediante un campo eléctrico en donde el polímero forma fibras que rápidamente se adelgazan a diámetros más pequeños del orden de nm y µm, esta técnica de electrohilado tiene sus orígenes en los Estados Unidos en la década de los 30's con otra serie de patentes procuradas por Formahls, haciéndose popular hasta la década de los 90's, donde tiene su mayor auge con fines cercanos a la industria textil, está técnica es propuesta para su uso en Salud particularmente en la ingeniería de tejidos, reparación de tejidos y, liberación de drogas. Nuestra propuesta es construir un equipo que incorpora a la técnica de electrospinning: dispositivo para un rango de movimiento de 360° (2prad) a lo largo del eje del chorro, dispositivo para mezclar dos o tres polímeros, dispositivo para variar la distancia entre lo positivo electrodo y el electrodo negativo y también una caja que protege al usuario.

- Abstract:
A brief description of the electrospinning technique, scope, current applications and a proposal for the development of computers that is relatively simple to implement, in educational institutions or research centres. The first results of cactus mucilage for the development of cell frames. Recently a technique called electrospinning is proposed for cellular development frameworks (scaffolding three-dimensional), devices that provide the support necessary for cell proliferation and maintenance of their differentiated functions and biological signals required for the conservation of specific gene expression also defines the tissue architecture. The technique of electrospinning is that a polymer solution is forced through a nozzle by an electric field where the polymer fibres that form rapidly tapering to smaller diameters on the order of nm and µm, this technique has its origins in the United States in the late 30's with another series of patents procured by Formahls, became popular until the early 90's, where it has its peak with the end near the textile industry is technique is proposed for use in health particularly in tissue engineering, tissue repair and drug release. Our proposal is to synthesize making a biomaterial composite deposit of calcium through technique to form a scaffold that simulates three-dimensional bone tissue. Our proposal is to build a computer that incorporates the technique of electrospinning: a device for a range of motion of 360° (2prad) along the jet axis, a device for mixing two or three polymers, a device for varying the distance between the positive electrode and negative electrode and also a box that protects the user.
