A Patient‐Specific 3D Printed Carotid Artery Model Integrating Vascular Structure, Flow, and Endothelium Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

3D Bioprinted Renal Constructs Using Kidney‐Specific ECM Bioink System on Kidney Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
A kidney‐specific bioink derived from decellularized porcine kidney tissue supports the encapsulation, viability, and maturation of human primary kidney cells within 3D bioprinted constructs. In vivo, it also promotes the recruitment of host renal progenitor cells, collectively enhancing structural and functional regeneration of renal tissue.

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...
