Radiotherapy employs high-energy ionizing radiation to inflict DNA damage on cancer cells, thereby causing their demise. However, this procedure can inadvertently harm healthy tissue. Thus, this study aimed to develop biodegradable radiosensitizers that counteract these adverse effects by enhancing the radiation sensitivity of tumor cells and safeguarding normal cells. A biodegradable radiosensitizer was engineered by incorporating hafnium ions (Hf) into calcium carbonate (CaCO) nanoparticles via a chemical precipitation technique, resulting in the formation of Hf:CaCO nanoparticles. Our findings demonstrate that Hf:CaCO nanoparticles exhibit pH-dependent solubility and can augment the efficacy of radiotherapy in treating cancer cells. This research underscores the potential of Hf:CaCO nanoparticles as a dual-modality radiosensitizer in radiotherapy.

Lignin has emerged as a sustainable alternative to fossil-based polymers in advanced materials such as photonics. However, current methods for preparing photonic lignin materials are limited by non-benign organic solvents and low production yields. In this work, we present a highly efficient process that enables the production of photonic glasses with yields ranging from 48% to 72%, depending on the size of the lignin nanoparticles obtained from herbaceous soda lignin, softwood kraft lignin, and hardwood organosolv lignin.

Myocardial infarction (MI) is a leading cause of morbidity and mortality worldwide, and mitigating oxidative stress is crucial in managing MI. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a critical role in combating oxidative stress and facilitating cardiac remodeling post-MI. Here, we engineered Cerium oxide (CeO) nanoparticle-guided assemblies of ceria/Nrf2 nanocomposites to deliver Nrf2 plasmids.
