摘要：Paper devices have recently attracted considerable attention as a class of cost-effective cell culture substrates for various biomedical *** paper biomaterial can be used to partially mimic the in vivo cell microenvironments mainly due to its natural three-dimensional *** paper-based devices provide precise control over their structures as well as cell distributions,allowing recapitulation of certain interactions between the cells and the extracellular *** features have shown great potential for the development of normal and diseased human tissue *** this review,we discuss the fabrication of paper-based devices for in vitro tissue modeling,as well as the applications of these devices toward drug screening and personalized *** is believed that paper as a biomaterial will play an essential role in the field of tissue model engineering due to its unique performances,such as good biocompatibility,eco-friendliness,cost-effectiveness,and amenability to various biodesign and manufacturing needs.
