Polymer-based microfluidic chip production is ideally suited for high-volume, low-cost applications such as bedside diagnostics, quality control in the field and rapid sample preparation for analysis. A range of different techniques are used that make it possible to produce microscopic patterns on macroscopic parts, which is a characteristic of microfluidics. Some techniques are mostly used in research and development (R&D), while others are perfectly suited for industrial-scale production.
