This article provides an overview of the advances in biomaterials for the construction of organs-on-chips. It introduces the composition, structure, and fabrication techniques of biomaterials, and focuses on their functions and applications in organs-on-chips systems. The use of biomaterial-based organs-on-chips as alternative animal models and the challenges and prospects of further functionalization are also discussed.
Organs-on-chips are microengineered microfluidic living cell culture devices with continuously perfused chambers penetrating to cells. By mimicking the biological features of the multicellular constructions, interactions among organs, vascular perfusion, physicochemical microenvironments, and so on, these devices are imparted with some key pathophysiological function levels of living organs that are difficult to be achieved in conventional 2D or 3D culture systems. In this technology, biomaterials are extremely important because they affect the microstructures and functionalities of the organ cells and the development of the organs-on-chip functions. Thus, herein, we provide an overview on the advances of biomaterials for the construction of organs-on-chips. After introducing the general components, structures, and fabrication techniques of the biomaterials, we focus on the studies of the functions and applications of these biomaterials in the organs-on-chips systems. Applications of the biomaterial-based organs-on-chips as alternative animal models for pharmaceutical, chemical, and environmental tests are described and highlighted. The prospects for exciting future directions and the challenges of biomaterials for realizing the further functionalization of organs-on-chips are also presented. The advances in biomaterials for the construction of organs-on-chips are reviewed, including the design, fabrication, functions, applications, and future directions of these biomaterial-based platforms.
