Porous Coatings by Vapor Sublimation and Deposition for Molecular Channeling and Filtration in an Interstitial Fluid Microfiltration Device

open access: yesAdvanced Healthcare Materials, EarlyView.
A vapor‐based porous coating applied within nitinol tubes demonstrated complete suppression of cellular and tissue ingrowth, overcoming a major limitation of implantable interstitial fluid collection devices. Molecular channeling and diffusion are analyzed with probe molecules, showing reliable transport in vitro and in vivo. The coating also achieved >

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

open access: yesAdvanced 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 ...

Cryopreserved Human Otic Neuronal Spheroids Self‐assemble for Functional Connectivity Analysis and Long‐term Ototoxicity Evaluation

open access: yesAdvanced Science, EarlyView.
This study establishes a robust and reproducible protocol for generating human otic neuronal spheroids (hONS) from cryopreserved hPSC‐derived pre‐placodal ectoderm cells. These hONS further differentiate into functional SGN‐like neurons, which extend neurite projections toward both murine hair cells and human cortical organoids, thereby forming ...
