Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of

Magnetic‐Driven Torque‐Induced Electrical Stimulation for Millisecond‐Scale Wireless Neuromodulation

open access: yesAdvanced Healthcare Materials, EarlyView.
MagTIES is a wireless neuromodulation technique with millisecond precision. It employs magnetic‐driven torque from magnetite nanodiscs to activate piezoelectric nanoparticles, enabling precise temporal control of neuronal activity and brain oscillations using weak, low‐frequency magnetic fields.

Lymphoid and CXCR4 Cell Targeted Lipid Nanoparticles Facilitate HIV‐1 Proviral DNA Excision

open access: yesAdvanced Healthcare Materials, EarlyView.
Advancements in ART improve HIV‐1 patient outcomes but are unable to eliminate latent viral DNA. To address this, CXCR4‐targeted lipid nanoparticles (T‐LNPs) for delivering CRISPR‐Cas9 to excise HIV‐1 DNA in infected cells are developed. These T‐LNPs achieve ≈60% HIV‐1 DNA excision efficacy in blood and splenic tissue, demonstrating promise for ...

Coagulation Matters: ATIII‐Enriched Biomolecular Corona Enhances the Hemocompatibility of PEG Nanoparticles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineering of a functional protein corona with a synergistic heparin‐ATIII complex significantly improves hemocompatibility of PEG nanoparticles. Through deliberate engineering of the protein corona, a 4‐fold reduction in coagulation activation (F1 + 2) without inducing adverse thromboinflammatory reactions (CD11b, C5a) is achieved without disrupting ...

Imiquimod‐Loaded Phospholipid‐Free Small Unilamellar Vesicles Activate the Tumor Immune Microenvironment to Treat Liver Cancer and Liver Metastases

open access: yesAdvanced Healthcare Materials, EarlyView.
Imiquimod‐loaded nanoparticles (PFSUV‐IMQ) are found to decrease liver metastasis and liver tumor burden when administered intravenously. Flow cytometry, RNA‐seq and various experiments show that the anti‐tumor response is immune‐mediated by activating dendritic cells resulting in increased CD8 T cell infiltration and activity.

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.
