Tailoring Piezoelectric Nanogenerators and Microdevices for Cellular Excitation: Impact of Size and Morphology

open access: yesAdvanced Science, EarlyView.
Piezoelectric microdevices, composed of ZnO nanosheets acting as nanogenerators and grown on silicon microparticles, are designed and fabricated to deliver precise electrical cell stimulation. This study optimizes nanosheet growth and microparticle size to enhance electrical cell activation performance while minimizing cellular internalization.

Mechanisms of Baicalin Alleviates Intestinal Inflammation: Role of M1 Macrophage Polarization and Lactobacillus amylovorus

open access: yesAdvanced Science, EarlyView.
Baicalin alleviates E. coli‐induced intestinal inflammation through dual mechanisms: direct inhibition of the TLR4/IRF/STAT signaling pathway to modulate macrophage polarization and antigen presentation, thereby regulating Th17/Treg cell differentiation; and microbiota‐mediated indirect effects via increasing Lactobacillus amylovorus abundance and ...

Nanoneedle‐Based Electroporation for Efficient Manufacturing of Human Primary Chimeric Antigen Receptor Regulatory T‐Cells

open access: yesAdvanced Science, EarlyView.
Low reproducibility and inefficient gene transfer hamper clinical manufacturing of chimeric antigen receptor regulatory T cells (CAR Tregs). Nanoneedle mediated electroporation generates primary human CAR Tregs under good manufacturing practice conditions with superior efficiency compared to viral transduction.

Viridicatol from the Deep‐Sea‐Derived Fungus Alleviates Bone Loss by Targeting the Wnt/SHN3 Pathway

open access: yesAdvanced Science, EarlyView.
Viridicatol (VDC), isolated from the deep‐sea‐derived fungus, enhances osteogenesis in vitro and in vivo by targeting Wnt/SHN3 signaling pathway. It can be delivered via engineered nanovesicles to mitigate bone loss of osteoporosis, fracture repair, and osteogenesis imperfecta.

Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores

open access: yesAdvanced Science, EarlyView.
A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.

Bioorthogonal Reaction of o‐Quinone with Furan‐2(3H)‐One for Site‐Selective Tyrosine Conjugation and Construction of Bispecific Antibody Complexes

open access: yesAdvanced Science, EarlyView.
A site‐selective, efficient, and mild tyrosine conjugation via tyrosinase oxidation and nucleophilic addition, allowing for site‐selective functionalization of peptides, recombinant proteins, and IgGs. Site‐selective mono‐functionalization of IgGs at Y296 enables the construction of immunoliposomes.

Manipulation of Oxygen Tension in Damaged Regions via Hypoxia‐Induced IPN Hydrogel Microspheres for Intervertebral Disc Regeneration

open access: yesAdvanced Science, EarlyView.
A novel interpenetrating network hydrogel microsphere (NSC‐Exos@HIMS) is developed to manipulate oxygen tension in damaged regions and recruit endogenous stem cells. In vitro and in vivo results show that NSC‐Exos@HIMS maintains the hypoxia microenvironment for up to 5 days, which triggers nucleus pulposus cell‐like differentiation and enhanced ECM ...

SCORT–Cas13d Nanotherapy Precisely Targets the ‘Undruggable’ Transcription Factor HoxB13 in Metastatic Prostate Cancer In Vivo

open access: yesAdvanced Science, EarlyView.
SCORT–Cas13d–pre‐gHoxB13 lipid nanoparticles precisely deliver Cas13d mRNA and guide RNAs to metastatic prostate tumors in the liver, knocking down the “undruggable” transcription factor HoxB13. This approach suppresses metastatic tumor growth, extends mouse survival, and does not induce major organ toxicity or immune activation, offering a safe and ...

New Insights into Heavy Metal Sequestration Through Metal‐Phenolic Network‐Confined Nano‐HFO: Overlooking Iron Utilization and Modulating Electron Density

open access: yesAdvanced Science, EarlyView.
Iron‐based nanocomposites are widely used for trace heavy metal removal, but the low utilization of HFO nanoparticles remains a challenge. Here, a metal‐phenolic network (MPN) strategy is proposed to confine nano‐HFO within polystyrene beads, creating a negative electrostatic field and optimizing electron density at oxygen sites. This approach enhances
