Developments in plasma-polymerized films used for the design of chip-based biosensors, commonly referred to as biochips, are described. Plasma-polymerized films are suitable for the design of an interface between biological components and physical transducers, which are the two well-known main parts of biochips. The roles and advantages of plasma-polymerized films in biochip design are highlighted. Mainly, plasma-polymerized films can play an important role in the control and manipulation of biological components on different spatial regions (patterning), while retaining their activity. In addition, dry-process-based plasma-polymerization are compatible with biochip fabrication processes.
