Apparatus For Producing Paper-Based Chemical Assay Devices

摘要

An apparatus produces chemical assay devices from a hydrophilic substrate, hydrophobic materials, and a chemical reagent. The apparatus includes a first print zone that forms hydrophobic material in a predetermined arrangement on the hydrophilic substrate, a structure formation unit configured to enable the first layer of the hydrophobic material to penetrate the hydrophilic substrate.

1. An apparatus for producing chemical assay devices comprising:
a substrate transport configured to move a first hydrophilic substrate in a process direction; a first print zone including at least one printhead configured to eject a first plurality of drops of a hydrophobic material to form a first layer of the hydrophobic material in a predetermined arrangement on a first side of the first hydrophilic substrate; and a structure formation unit positioned in the process direction after the first print zone and configured to apply heat and pressure to the first hydrophilic substrate after the first plurality of drops of hydrophobic material are ejected onto the first hydrophilic substrate to enable the first layer of the hydrophobic material to penetrate the first hydrophilic substrate to form hydrophobic structures in the first hydrophilic substrate.
