Programmed Aggregation of Lipidated Nitrobenzoselenadiazole as a Photo‐Activatable Pyroptosis Inducer

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents alkylated nitrobenzoselenadiazole (NBSD) photosensitizers that self‐assemble into programmable aggregates, enabling photo‐triggered pyroptosis and enhanced ROS generation. The lead compound, NBSD‐NOc, exhibits superior photodynamic activity, high cellular uptake, and implantable gel compatibility with pH‐responsive release.

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.

Tumor Microenvironment‐responsive Nanocatalyst for Targeted Chemodynamic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An Tumor microenvironment‐responsive nanocatalyst system composed of PLGA‐encapsulated Ca–Fe peroxide and polyarginine enables sustainable Fenton reaction in tumors. Low levels of H2O2 (50–100 µm) initiate the nanoparticle degradation, while polyarginine‐derived nitric oxide accelerates Fe3+ reduction, leading to self‐amplifying •OH generation for ...

DNA Barcoding‐Enabled Tracking of Lipid Nanoparticles: Drug‐Loading‐Dependent Biodistribution and Tumor Microenvironment Targeting

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, lipid nanoparticles are tracked in vivo using DNA barcodes to determine how varying drug loadings affect their delivery behaviors in mice. A cost‐effective strategy is developed for simultaneously monitoring the biodistribution of a library of lipid nanoparticles (LNPs).
