Nuestro blog se ha creado como trabajo de la asignatura Métodos Electroanalíticos Avanzados de quinto curso de Licenciatura en Química. Su principal objetivo es describir los microelectrodos y sus aplicaciones en el análisis químico, tales como: medidas en sistemas biológicos, detección en sistemas en flujo y microelectrodos modificados. Para conseguirlo se utilizará información de la Red (vídeos, fotografías, documentos, blogs, páginas web...), textos y artículos académicos que serán agregados como entradas y conformarán el corpus del blog.

Generalidades sobre microelectrodos:

Los microelectrodos poseen al menos una dimensión micrométrica, aceptándose comúnmente que esta dimensión "crítica" no debe sobrepasar los 50 micrometros para que puedan observarse sus propiedades características, como la minimización de los efectos de caída óhmica; la capa de difusión puede sobrepasar las dimensiones del electrodo y disminuye la corriente de carga. Se utilizan microelectrodos de diversas geometrías, siendo las más frecuentes las de disco, la cilíndrica y la configuración de series de microelectrodos ("array"), que contiene varios elementos independientes entre sí. En cuanto a los materiales, los más empleados son la fibra de carbono y el carbono vitrificado, y el platino y el oro, entre los metales.
