Stable and well-characterized surfaces are essential for medical and diagnostic applications using microfluidic devices. Surface coating strategies can be classified into two major categories: covalent and adsorptive coatings. For covalent coating methods, the most common strategies are discussed based on the chemical characteristics of the device material. Furthermore, major classes of adsorptive coating strategies are presented, compared to their covalent counterparts, and discussed in relation to their respective importance in medical and diagnostic applications.
