One of the main drivers in healthcare technology is the development of new devices and technologies that enable earlier, faster and more frequent diagnostic testing and personalized medicine. Point-of-Care (PoC) diagnostic devices allow medical tests to be performed in the vicinity of the patient instead of in a clinical laboratory. Compared to current solutions, microfluidic devices promise to enable the development of PoC devices for more complex diagnostic tests.
For PoC applications, large numbers of microfluidic cartridges have to be produced at low cost. This can be achieved by injection molding of thermoplastics. However, several technical challenges still exist when it comes to combining the manufacturing of the cartridge with other crucial processes such as on-chip storage of reagents, application of coatings and bonding of the device.
