Non‐Invasively Quantitative Raman Imaging for Calculation of Lymphatic Transport Kinetics of Micelles in Mice

open access: yesAdvanced Science, EarlyView.
Non‐invasively quantitative Raman imaging with stacking‐induced charge transfer‐enhanced Raman scattering (SICTERS) enables accurate measurement of concentrations and pharmacokinetic modeling of lymphatic transport of micelles in mice. This platform allows dynamic analysis of nanoparticle transport and underpins the design of effective lymph node ...

Beyond Conventional: A Review of Phytochemical‐Hydrogel Systems Enhanced by AI and 3D Printing for Chronic Wound Management

open access: yesAdvanced Science, EarlyView.
This review systematically bridges chronic wound pathology with natural phytochemical hydrogel therapeutics. A pathology‐to‐phytochemical mechanistic mapping framework is established, linking specific wound hallmarks to targeted phytochemical interventions.

Dual‐Targeted Biomimetic MoSe2 Nanozymes for Enhancing Peri‐Implant Soft Tissue Integration

open access: yesAdvanced Science, EarlyView.
A dual‐targeting biomimetic nanozyme, MoSe2@SPMM, selectively targets Staphylococcus aureus and oxidatively stressed macrophages. Near‐infrared activation couples contact‐enhanced photothermal bacterial eradication with reactive oxygen species scavenging to disrupt the pathogenic–immunological amplification loop.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

Programmable Self‐Heating Microneedle Patch for on‐Demand Postprandial Glucose Management

open access: yesAdvanced Science, EarlyView.
A programmable self‐heating microneedle patch enables on‐demand, timed‐sequence insulin delivery via user‐triggered quadrant activation. Each activation generates localized heat that melts a phase‐change barrier, accelerating drug release. In diabetic rats, sequential quadrant activation counteracts four meal‐mimicking glucose spikes over 24 h without ...

Echocardiography-guided percutaneous closure of oval-shaped secundum atrial septal defects

open access: yesBMC Cardiovascular Disorders
Background An atrial septal defect (ASD) is considered oval-shaped when its shortest diameter is less than 75% of the longest diameter. Research on percutaneous closure of oval-shaped ASDs is limited, with no known reports of non-fluoroscopic closure for

Targeted‐Penetrating Biomimetic Hybrid Transfersomes for Enhanced Transdermal Gene Transfection in Hypertrophic Scar Therapy

open access: yesAdvanced Science, EarlyView.
Hypertrophic scar fibroblasts membrane‐hybridized cationic transfersomes enable efficient loading and transdermal delivery of TGF‐β1 siRNA through multiple skin penetration pathways. The biomimetic platform enhances homotypic targeting, transfection, and immune evasion, suppresses TGF‐β1‐driven fibrotic signaling, and reduces extracellular matrix ...

Versatile Microgel Platform for Intervertebral Disc Degeneration Therapy: Targeting Pericyte‐Mediated Fibrosis and Protecting Nucleus Pulposus Cells

open access: yesAdvanced Science, EarlyView.
The engineered MMS@TRP microgel enables targeted, acid‐responsive delivery of a miR‐21 inhibitor to pericytes. It effectively suppresses disc fibrosis by inhibiting TGF‐β signaling while protecting nucleus pulposus cells via sustained, antioxidant tannic acid release.
