Integration of ex situ fabricated porous polymer monoliths into fluidic chips
Bare porous polymer monoliths, fluidic chips, methods of incorporating bare porous polymer monoliths into fluidic chips, and methods for functionalizing bare porous polymer monoliths are described. Bare porous polymer monoliths may be fabricated ex situ in a mold. The bare porous polymer monoliths may also be functionalized ex situ. Incorporating the bare preformed porous polymer monoliths into the fluidic chips may include inserting the monoliths into channels of channel substrates of the fluidic chips. Incorporating the bare preformed porous polymer monoliths into the fluidic chips may include bonding a capping layer to the channel substrate. The bare porous polymer monoliths may be mechanically anchored to channel walls and to the capping layer. The bare porous polymer monoliths may be functionalized by ex situ immobilization of capture probes on the monoliths. The monoliths may be functionalized by direct attachment of chitosan.
