Investigation on the Influence of Protein Corona and Platelet Adhesion on Storage Bag Surface on the Platelet Storage Lesion

Advanced Healthcare Materials, EarlyView.
Platelet quality deteriorates during storage due to protein and platelet adhesion to current bag materials. Here, polymer coatings are identified that reduce adhesion and translated them to mini‐storage bags. Platelet quality are not impacted, despite significantly reducing adhesion.

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

Advanced 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.
