Abstract

Procedimiento para la determinación de la respuesta biológica de un objetivo (41; 41, 42) frente a una sustancia candidata soluble, procedimiento que comprende las siguientes etapas: - la introducción de una sustancia candidata soluble en un flujo laminar de un líquido tamponante (2) que fluye a través de un canal de dispersión (11) para formar un soluto de una sustancia candidata (3) en el líquido tamponante (2) que tiene un perfil de concentración inicial (31); - mediante el flujo laminar del líquido tamponante (2) a través del canal de dispersión (11) que dispersa el perfil de concentración inicial (31) del soluto de una sustancia candidata (3) en el líquido tamponante (2) para formar un perfil de concentración dispersado (32) del soluto de una sustancia candidata (3) en el líquido tamponante (2); - dirigir el flujo laminar del líquido tamponante (2) que contiene el soluto de una sustancia candidata (3) que tiene el perfil de concentración dispersado (32) a un canal de detección (12) para formar un perfil de concentración simétrico final (33) del soluto de una sustancia candidata (3) en el líquido tamponante (2) en el canal de detección (12); - la introducción de un objetivo en el canal de detección (12) (41; 41, 42) de tal forma que se obtenga un perfil de concentración combinado en el líquido tamponante (2), perfil de concentración combinado que comprende un perfil de concentración del objetivo constante suprayacente al perfil de concentración simétrico final (33) del soluto de una sustancia candidata (3) ; - mantener en el canal de detección (12) al menos una mitad del perfil de concentración combinado contenido en el líquido tamponante; y - llevar a cabo un barrido óptico de la al menos una mitad del perfil de concentración combinado contenido en el líquido tamponante mantenido en el canal de detección (12) para detectar, a las diversas concentraciones del soluto de una sustancia candidata (3) del perfil de concentración combinado, una señal óptica que sea representativa de la respuesta biológica del objetivo (41; 41, 42) frente a la sustancia candidata soluble.
