Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Three‐Dimensional Ovary Model to Improve and Study Murine Follicle Growth

open access: yesAdvanced Healthcare Materials, EarlyView.
To develop new methods for fertility preservation in women, novel culture systems for small follicles need to be established. In this work, a poly(ethylene glycol) based scaffold, with appropriate mechanical and bioactive features to support mouse follicle and ovary cell growth is developed, and the formed cell‐follicle interactions are visualized ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced 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 ...
