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

open access: yesAdvanced 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.

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 ...

Biologically Active Implants Prevent Mortality in a Mouse Sepsis Model

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular, triple‐action titanium implant is developed to prevent implant‐associated infections by repelling bacteria, killing pathogens, and enhancing tissue integration. Coatings with phage cocktails targeting P. aeruginosa and S. aureus show significant bacterial reduction and improved survival in a mouse sepsis model.
