Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

open access: yesAdvanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

open access: yesAdvanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.
