Hydrogel Microneedle Array‐Based Transdermal Dressing System for Multiplexed Assessment and Intelligent Therapy of Chronic Wounds (Small 10/2026)

Chronic Wounds In article number e11542, Zeynep Altintas and co-workers present a hydrogel microneedle dressing that penetrates the epidermis and reaches to the dermis to continuously sample wound interstitial fluid, enabling real-time diagnostics and intelligent chronic-wound therapy. Laser-scribed PEDOT:PSS electrodes on an antibacterial MXene-infused hydrogel provide multiplexed sensing of seven biomarkers, delivering biochemical insights and personalized treatment beyond surface exudate monitoring.
