Fluidic Assay Cartridge With Controlled Passive Flow

摘要

A fluidic cartridge (110) with passively driven fluid flow is disclosed. The disclosed device and method solve problems associated with passive-flow fluidics by using a wicking pad (510) and/or a tilting means to prevent channel draining and backflow. The disclosure further provides means for adding liquid to the cartridge in multiple steps, without requiring liquid aspiration or removal.
