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.

Lymphoid and CXCR4 Cell Targeted Lipid Nanoparticles Facilitate HIV‐1 Proviral DNA Excision

Advanced Healthcare Materials, EarlyView.
Advancements in ART improve HIV‐1 patient outcomes but are unable to eliminate latent viral DNA. To address this, CXCR4‐targeted lipid nanoparticles (T‐LNPs) for delivering CRISPR‐Cas9 to excise HIV‐1 DNA in infected cells are developed. These T‐LNPs achieve ≈60% HIV‐1 DNA excision efficacy in blood and splenic tissue, demonstrating promise for ...

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

Advanced 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 ...

Biphasic Granular Bioinks for Biofabrication of High Cell Density Constructs for Dermal Regeneration

Advanced Healthcare Materials, EarlyView.
This study introduces a biphasic granular bioink (µInk) that enables 3D bioprinting of high cell density constructs for dermal regeneration. The bioink promotes cell proliferation, ECM deposition, and neovascularization, leading to tissue integration and reduced scar formation in vivo.
