Freeze-printing of pectin/alginate scaffolds with high resolution, overhang structures and interconnected porous network

Additive Manufacturing 2021 Volume 46, Article 102120

We report herein the fabrication of a pectin-based scaffold (6 wt% pectin, 3 wt% alginate) with high resolution (small-diameter rods), small pores, and interconnected porosity using a low temperature 3D printing process known as freeze-printing. The ability to successfully print natural polymers has been a long-standing challenge in the field of additive manufacturing of polymeric tissue scaffolds. This is due to the slow evaporation rate of the aqueous solvent, which leads to unstable structures. This problem has been addressed by utilizing the fast solidification rate of the freeze-printing process. Scaffolds with a hgresolution (rod-diameter of 83 ± 14 µm), small…

Multi-compartment Organ-on-a-Chip Based on Electrospun Nanofiber Membrane as In Vitro Jaundice Disease Model

Advanced Fiber Materials 2021 Volume 3, Pages 383–393

Organ-on-a-chip (OOC) is now becoming a potential alternative to the classical preclinical animal models, which reconstitutes in vitro the basic function of specific human tissues/organs and dynamically simulates physiological or pathological activities in tissue and organ level. Despite of the much progress achieved so far, there is still an urgent need to explore new biomaterials to construct a reliable and efficient tissue–tissue interface and a general fabrication strategy to expand from single-organ OOC to multi-organ OOC in an easy manner. In this paper, we propose a novel strategy to prepare double-compartment organ-on-a-chip (DC-OOC) using electrospun poly(l-lactic acid)/collagen I (PLLA/Col I)…
