A Biomimetic Norepinephrine‐Loaded Aligned Mineralized Collagen Scaffold for Coordinated Neurovascular, Osteogenic, and Immunomodulatory Repair of Critical‐Sized Bone Defects

Advanced Science, EarlyView.
Inspired by the composition and structure of native bone tissue and its complex interplay of biological signals, a norepinephrine‐loaded biomimetic mineralized electrocompacted collagen scaffold (NE‐MEC) is developed capable of simultaneously supporting osteogenesis, neural repair, angiogenesis, and immune modulation.

Modelling the backwash process in micro filtration [PDF]

, 1991
Microfiltration separates fine solids from a liquid substrate, but requires a process to remove the accumulated solids from the filtering device. In this study, a backwash process was examined, in which a flow of high-pressure air in the direction ...

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

Advanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Immunoaffinity‐Mimetic Assembly of Peptide‐Aptamer Conjugates and Stem Cell‐Derived Exosomes into Hierarchical Microgels for Spinal Cord Injury Repair

Advanced Science, EarlyView.
Inspired by antibody‐antigen binding, this study develops an unprecedented immunoaffinity‐mimetic assembly strategy, with Peptide‐AptCD63 conjugates acting as antibody surrogates binding CD63 epitopes on mesenchymal stem cell‐derived exosomes. This creates a hierarchical microstructure intended to synergistically integrate antioxidative and anti ...

Anionic Liposomes as Optimal Membrane Fusion Carriers Enabling in Situ Multiplexed Detection of Extracellular Vesicle MicroRNAs

Advanced Science, EarlyView.
A novel strategy for in situ multiplexed miRNA analysis of plasma extracellular vesicles (EValarm) has been developed. EValarm enables straightforward detection of different extracellular vesicle miRNAs from plasma samples through systematic screening of liposome surface charges, without requiring complex pretreatment steps, and achieves satisfactory ...

Microglial Membranes Wrapped Ultrasmall Medium‐Entropy Ru Single‐Atom Nanozyme: Enhanced Catalysis for Accelerating Inflammation/Redox Microenvironment Regulation in Intracerebral Hemorrhage

Advanced Science, EarlyView.
PtRhIr/Ru SAN@M nanozymes cross the blood–brain barrier and selectively accumulate in hemorrhagic brain regions. By mimicking multiple enzyme activities, they attenuate oxidative stress, modulate microglial polarization toward an anti‐inflammatory phenotype, inhibit ferroptosis, and promote neuronal repair.
