Abstract
"dispositivo de análise de fluxo lateral com controle de fluxo de filtração", por trar a presente invenção de um dispositivo de análise de fluxo lateral que inclui um substrato com uma zona de adição de amostra e uma trajetória de fluxo de fluido. uma cobertura suporta um filtro que tem uma porção que faz contato com o substrato para criar uma área de contato que ao menos parcialmente se sobrepõe à zona de adição de amostra. outra porção se estende a partir da porção de contato até a periferia suportada do filtro, para definir com o substrato um reservatório configurado para reter o filtrado por pressão capilar entre o substrato e a porção que se estende do filtro. o volume do reservatório se baseia em um ângulo agudo formado entre o substrato e a porção que se estende do filtro e em um menisco de fluido do filtrado. o filtro e a zona de adição de amostra são configurados para fornecer pressão capilar que drena o filtrado do reservatório para a zona de adição de amostra. métodos para controlar as características do fluxo em um dispositivo de análise de fluxo lateral são também descritos.
