Article Abstract
In this work, we elucidate polymer-layered hollow Prussian blue-coated magnetic nanocomposites as an adsorbent to remove radioactive cesium from environmentally contaminated water. To do this, Fe₃O₄ nanoparticles prepared using a coprecipitation method were thickly covered with a layer of cationic polymer to attach hollow Prussian blue through a self-assembly process. The as-synthesized adsorbent was confirmed through various analytical techniques. The adsorbent showed a high surface area (166.16 m²/g) with an excellent cesium adsorbent capacity and removal efficiency of 32.8 mg/g and 99.69%, respectively. Moreover, the superparamagnetism allows effective recovery of the adsorbent using an external magnetic field after the adsorption process. Therefore, the magnetic adsorbent with a high adsorption efficiency and convenient recovery is expected to be effectively used for rapid remediation of radioactive contamination.

Individuals diagnosed with inflammatory bowel disease (IBD) exhibit a markedly elevated prevalence of psychiatric disorders, particularly anxiety and depression. However, the underlying mechanisms contributing to the development of these psychiatric conditions in IBD patients remain poorly understood, and no effective therapeutic strategy has been definitively established. Recent advancements in nanotechnology-based interventions offer promising potential for restoring gut homeostasis, which may mitigate inflammation and oxidative stress associated with IBD.

Immunogenic cell death (ICD)-induced anti-tumor immune responses are pivotal for achieving therapeutic efficacy and long-term protection. Tumor cell fragments following disulfide death can induce immunogenic cell death by promoting antigen presentation and increasing cytotoxic T lymphocytes (CTL) infiltration. Herein, oxygen-driven Prussian blue nanomotors (GOx@HPB) were developed by disrupting the redox state to induce disulfidptosis for tumor immunotherapy.

Photothermal therapy for bacterial infections poses a significant challenge due to the high temperatures required for effective bacterial eradication, which can also harm surrounding healthy tissues. Determining the minimal effective temperature for bacterial destruction is therefore critical. In this study, artificial reef-like manganese-doped Prussian blue (PBMn) nanoframes are developed as photothermal agents and physical cross-linkers to reinforce a phytic acid and cationic polymer network coating.
