Macrophage Membrane‐Camouflaged Nanozyme Microneedles Restore Immunovascular Homeostasis Through SPP1‐ApoE Signaling in Diabetic Wounds

open access: yesAdvanced Healthcare Materials, EarlyView.
Macrophage membrane‐coated Cu/Zn‐MOF nanozyme microneedles (MNs) reprogram the diabetic wound microenvironment through localized, minimally invasive delivery. By suppressing M1‐like macrophage activation while promoting extracellular matrix deposition and angiogenesis, this biomimetic platform accelerates diabetic wound repair.

Bioactivity of degradable polymer sutures coated with bioactive glass

open access: yesJournal of Materials Science: Materials in Medicine, 2004
Novel bioactive materials have been prepared by coating violet resorbable Vicryl sutures with a bioactive glass powder derived from a co-precipitation method. Two techniques have been chosen for the composite preparation: pressing the sutures in a bed of glass powder and slurry-dipping of sutures in liquid suspensions of bioactive glass powders.

Encoded Cell‐Material Interactions to Reroute Cytokine Signaling for Regenerative Medicine

open access: yesAdvanced Healthcare Materials, EarlyView.
We present native MATRIX (Material Activated To Regulate Inducible gene eXpression), a co‐engineered material‐cell platform. Surfaces functionalized with antibodies for endogenous soluble ligands (e.g., IL‐1β or IL‐6) capture and immobilize ligands for presentation to a cognate, engineered synthetic Notch receptor, releasing a transcription factor (TF)

Multicomponent Peptide‐MXene‐Hyaluronic Acid Hydrogel as a Conductive Scaffold for Enhanced Fibroblast Proliferation and Migration Under Electrical Stimulation

open access: yesAdvanced Healthcare Materials, EarlyView.
An electrically conductive FmocFF/MXene/hyaluronic acid hydrogel combines extracellular matrix‐like architecture, self‐healing behavior, oxidation‐resistant conductivity, and biochemical cues in a single scaffold. By enabling physiologically relevant electrical stimulation, the platform enhances fibroblast attachment, proliferation, and migration ...

Study of the Bioactivity of Various Mineral Compositions of Bioactive Glasses

open access: yesBioceramics Development and Applications, 2011
Many types of bone substitutes exist to fill a bony defect. They must be compatible and bond with the host tissue without any formation of fibrous capsule. The direct apposition of bone to bioactive materials, including bioactive glasses and calcium phosphates, has already been demonstrated. In this work, different compns.
