A Modular Liver–Microbial Microfluidic Platform to Evaluate Therapeutic and Adverse Effects of Microbial Metabolites

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a modular microfluidic platform that connects liver cells with live microbes to mimic key aspects of the gut–liver interaction in steatosis. Using this system, both microbial metabolites and live bacteria significantly reduced fat accumulation in liver cells, but live microbes triggered inflammation and broader metabolic changes ...

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.

Mechanotransduction of Magnetically Applied Forces Leads to Mechanical Stiffening of Platelet‐Rich Plugs

open access: yesAdvanced Healthcare Materials, EarlyView.
A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)
