Development of a Human Recombinant Collagen for Vat Polymerization‐Based Bioprinting
Biotechnology JournalABSTRACTIn light‐based 3D‐bioprinting, gelatin methacrylate (GelMA) is one of the most widely used materials, as it supports cell attachment, and shows good biocompatibility and degradability in vivo. However, as an animal‐derived material, it also causes safety concerns when used in medical applications.

Fabrication of 3D conjugated polymer structures via vat polymerization additive manufacturing
Smart Materials and Structures, 2019 Conjugated polymers are a class of electroactive active material that have been studied for their potential in advanced sensing and actuation technologies. Conventional methods to fabricate conjugated polymer transducers produce devices with planar morphologies that limit fabricated devices to simplistic linear or bending modes of operation.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...
