Segmented Therapeutic Delivery via Acoustic Microbubble Relay

open access: yesAdvanced Intelligent Systems, EarlyView.
An acoustically driven, modular segmented delivery system is presented to overcome mechanical limitations of conventional microcatheters. Oscillating microbubbles generate directional streaming that enables continuous, targeted transport across open, angled segments.

A Non‐Covalent [4Fe–4S]/[2Fe] Interface in HydF Guides [FeFe]‐Hydrogenase Maturation

open access: yesAngewandte Chemie, EarlyView.
Bridged or not? 57Fe NRVS reveals a non‐covalent, electronically coupled interaction between the HydF [4Fe–4S] cluster and the [2Fe] precursor. Boltz‐2 structure predictions suggest that the cubane organizes lipoate‐dependent Hmet chemistry, positioning intermediates for assembly of the CH2–NH–CH2 bridge during H‐cluster biosynthesis.

Speech Biomarkers for Quantifying Effects of Subthalamic Deep Brain Stimulation in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Dysarthria is one of the most common and disabling side effects of subthalamic nucleus deep brain stimulation (STN‐DBS) in Parkinson's disease (PD). Stimulation often exacerbates speech dysfunction beyond the effects of PD progression, likely because of current spread to structures surrounding the STN.

Mechanically Regulated Nanozymes for Remote Metabolic Reprogramming and Precise Cancer Therapy

open access: yesAngewandte Chemie, EarlyView.
Inspired by mechanoenzymes, a ferrocene‐based mechanically regulated nanozyme converts acoustic shear force into enhanced peroxidase‐like activity by decreasing electron density and alleviating steric hindrance at the Fe active sites, thereby rewiring redox homeostasis. Leveraging this remote regulatory mechanism, a multienzyme‐regulated nanoreactor is
