Biofunctionalization of Glass‐ and Paper‐Based Microfluidic Devices: A Review

Biofunctionalization of microchannels is of great concern in the fabrication of microfluidic devices. Different substrates such as glass slides, papers, polymers, and beads require different biofunctionalization approaches granting the utilization of microfluidics in several biomedical applications. Covalent immobilization of biomolecules inside the microchannels is achieved by chemical modification of the surface such as silanization or...
