Resumen
En el presente artículo se ilustra el potencial que tienen los campos eléctricos no uniformes parala manipulación de micropartículas. Para ello se presentan los principios físicos que rigen elmovimiento de partículas eléctricamente neutras cuando son sometidas a campos eléctricosinhomogéneos. generandofenómenos tales como la dielectroforésis común (DE?). dielectroforésisde onda viajera (TWD) y la electrorotación (ROT). Además se presentan algunos resultados de laverificación experimental de una microestructura en espiral. fabricada en tecnología CMOS.cuya prueba se hizo con microesferas de poliestireno de 6 mm de diámetro. Por último se ilustrala manipulación de levaduras Saccharomyces cerevisiae mediante electrodos de platino queinducen en ellas elfenómeno de dielectroforésis común.
