Abstract

"PROCESSO PARA OPERAçãO DE UM SISTEMA DE MICROFLUIDO, SISTEMA DE MICROFLUIDO, FONTE DE ALIMENTAçãO DE POTêNCIA DE MICROFLUIDO E UTILIZAçãO DE UM SUBSTRATO, DE UMA FONTE DE ALIMENTAçãO DE POTêNCIA E DE UM SISTEMA DE MICROFLUIDO". Em um sistema de microfluido (parcialmente ilustrado pelo elemento 178 na figura e elementos sobre a mesma) utilizando forças eletrocinéticas, a presente invenção utiliza corrente elétrica ou parâmetros elétricos, diversos de voltagem, para controlar o movimento de fluidos através dos canais do sistema. Fontes de alimentação de potência multiplexadas por tempo (200 e 202) proporcionam igualmente um controle adicional sobre o movimento do fluido através da variação da voltagem em um eletrodo ligado a um reservatório de fluido do sistema de microfluido, através da variação do ciclo de trabalho durante o qual a voltagem é aplicada ao eletrodo, ou através de uma combinação de ambos. Uma fonte de alimentação de potência com multiplexação de tempo pode igualmente ser ligada a mais de um eletrodo para economizar custos.
