4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Bioprinting functional tissues

Acta Biomaterialia, 2019
Despite the numerous lives that have been saved since the first successful procedure in 1954, organ transplant has several shortcomings which prevent it from becoming a more comprehensive solution for medical care than it is today. There is a considerable shortage of organ donors, leading to patient death in many cases.

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

Advanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery

Advanced Science, EarlyView.
The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.
