A Novel Sprayable Fibrinogen/Glycosaminoglycans/Collagen‐Based Bioink for Skin Wound Healing Applied by a Handheld Dual‐Head Airbrush

Advanced Healthcare Materials, EarlyView.
A dual‐head airbrush‐based spraying device, combined with a fibrinogen bioink enriched with glycosaminoglycans and collagen, enables the delivery of biomaterials and cells to promote wound healing. This system demonstrates effective skin regeneration in vitro and in vivo, with comparable results to autografts.

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin

Advanced Healthcare Materials, EarlyView.
Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.

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

Advanced 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.

A Targeted Redox‐Active Dual‐Action Pt(IV)‐Mn(II) Prodrug Displays Enhanced In Vivo Anticancer Activity

Advanced Healthcare Materials, EarlyView.
A new oxaliplatin‐based Pt(IV) prodrug bearing a Mn(II) superoxide dismutase mimic is synthesized and studied, in vitro and in vivo, in the context of colorectal cancer. Encapsulation of this prodrug in an easy‐to‐implement PEGylated micelle formulation demonstrated the highest in vivo anticancer activity among all the tested conditions, supporting the

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

Advanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.
