ABSTRACT

Many complex steps, such as sample preparation, fluid handling, sample processing, and analysis, can be carried out seamlessly within the confines of a single CD. The CD, shown in Figure 13, is made up of intricate, molded microchannels in plastic, creating interconnected networks of fluid reservoirs and pathways. No pumps are required because spinning the CD moves the liquids around. What makes the technology versatile is the ability to rapidly and easily create application-specific CDs, where the applications are embedded in the intricate microstructures on the CD.
