Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

open access: yesAdvanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

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 ...

Multimaterial Microrobots for pH Sensing Fabricated Using Sequential 3D and 4D Printing with Automated Alignment

open access: yesAdvanced Materials Technologies, EarlyView.
This work proposes the use of multimaterial microrobots for pH sensing. The microrobots consist of a hard polymer backbone and 4D printed sensing elements made of a pH‐responsive hydrogel. The swelling response, reusability, and high mobility of the microrobots make them promising tools for pH sensing at the micro scale.

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides

open access: yesAdvanced Photonics Research, EarlyView.
Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...
