Animal‐Free Setup of a 3D Mature Adipocyte‐Macrophage Co‐Culture to Induce Inflammation In Vitro

open access: yesAdvanced Healthcare Materials, EarlyView.
A completely animal‐free 3D co‐culture is developed using human fat cells and immune cells. Animal‐based materials are replaced with gellan gum hydrogel and a serum‐free medium. Immune cells are effectively activated, producing specific inflammatory signals.

Nanocarrier‐Based Targeting of Pattern Recognition Receptors as an Innovative Strategy for Enhancing Sepsis Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
This review highlights recent progress in nanocarriers targeting pattern recognition receptors (PRRs), including Toll‐like and NOD‐like receptors, for enhancing the treatment of bacterial sepsis and related complications. These nanomedicines deliver antibiotics and anti‐inflammatory agents while modulating immune responses.

Toward Noninvasively Imaging pH at the Surface of Implanted Orthopedic Devices in Live Rabbits Using X‐ray Excited Luminescence Chemical Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Imaging pH in a live rabbit at the surface of a sensor‐coated titanium plate using X‐ray excited luminescent chemical imaging (XELCI). A raster scanning X‐ray beam generates radioluminescence from a spot on the sensor, and the luminescence passes through the tissue and is collected at two wavelengths to determine local pH.

Interstitial N‐Strengthened Copper‐Based Bioactive Conductive Dressings Combined with Electromagnetic Fields for Enhanced Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

Safety Evaluation of Repeated Application of Polymeric Microarray Patches in Miniature Pigs

open access: yesAdvanced Healthcare Materials, EarlyView.
This study demonstrates the safety of repeated application of three types of microarray patches (MAPs), hydrogelforming, dissolving, and implantable, over four weeks in miniature pigs. No adverse skin or systemic effects were observed, supporting the clinical potential of MAPs as safe and effective drug delivery platforms.
