Abstract

LAS VELOCIDADES DE CAPTACION DIELECTROFORETICAS DE MICROORGANISMOS Y DE OTRAS PARTICULAS DIELECTRICAMENTE POLARIZABLES ANIMADAS O INANIMADAS QUE SE ENCUENTRAN EN SUSPENSION EN UN FLUIDO SE ESTABLECEN HACIENDO FLUIR LOS ELECTRODOS PASADOS (17, 18) ENERGETIZADOS PARA PRODUCIR UN CAMPO ELECTRICO ALTERNO NO UNIFORME EN LA SUSPENSION, TERMINANDO LA ENERGETIZACION DE LOS ELECTRODOS DESPUES DE UN TIEMPO PREDETERMINADO PARA LIBERAR LAS PARTICULAS RECOGIDAS DE LA SUSPENSION Y, MEDIR, CORRIENTE ABAJO DE LOS ELECTRODOS, EL IMPULSO DE LAS PARTICULAS LIBERADAS COMO UNA MEDIDA DE LA VELOCIDAD DE CAPTACION DE PARTICULAS DURANTE LA ENERGETIZACION DE LOS ELECTRODOS. SI SE REPITEN LAS MEDIDAS A DIFERENTES FRECUENCIAS DE CAMPO SE PUEDE ESTABLECER UN ESPECTRO DE LA VELOCIDAD DE CAPTACION Y LA CARACTERIZACION O IDENTIFICACION DE LAS PARTICULAS BAJO EXAMEN MEDIANTE LA REFERENCIA DE LOS ESPECTROS CONOCIDOS DE PARTICULAS CONOCIDAS
