Biomaterials and Microfluidics for Drug Discovery and Development.

Microfluidic devices are now one of the most promising tools to mimic in vivo like conditions, either in normal or disease scenarios, such as tumorigenesis or pathogenesis. Together with the potential of biomaterials, its combination with microfluidics represents the ability to more closely mimic cells' natural microenvironment concerning its three-dimensional (3D) nature and continuous perfusion with nutrients and cells' crosstalk. Due to miniaturization and increased experimental throughput, microfluidics have generated significant interest in the drug discovery and development domain. Herein, the most recent advances in the field of microfluidics for drug discovery are overviewed, and the role of biomaterials in 3D in vitro models and the contribution of organ-on-a-chip technologies highlighted.
