Chemodynamic therapy (CDT), which induces cell death by decomposing high levels of H2O2 in tumor cells into highly toxic ·OH, is recognized as a promising antineoplastic approach. However, current CDT approaches are often restricted by the highly controlled and upregulated cellular antioxidant defense. To enhance ·OH‐induced cellular damage by CDT, a covalent organic framework (COF)‐based, ferrocene...
Engineered nanomaterials (ENMs) have huge potential for improving use efficiency of agrochemicals, crop production, and soil health; however, the behavior and fate of ENMs and the potential for negative long‐term impacts to agroecosystems remain largely unknown. In particular, there is a lack of clear understanding of the transformation of ENMs in both soil and plant compartments. The transformation...
In article number 2000705, Peng Zhang, Zhiyong Zhang, and co‐workers present a comprehensive review of nanomaterial transformation in the soil–plant system. Main knowledge gaps are highlighted, and future research needs are outlined so as to ensure sustainable nano‐enabled agricultural applications.
The release of metal ions may play an important role in toxicity of metal‐based nanoparticles. In this report, a life cycle study is carried out in a greenhouse, to compare the effects of ceria nanoparticles (NPs) and Ce3+ ions at 0, 50, 100, and 200 mg Ce kg−1 on plant growth, biological and physiological parameters, and nutritional value of soil‐grown common bean plants. Ceria NPs have a tendency...
Hydrogels are emerging biomaterials with desirable physicochemical characteristics. Doping of metal ions such as Ca2+, Mg2+, and Fe2+ provides the hydrogels with unique attributes, including bioactivity, conductivity, and tunability. Traditionally, this doping is achieved by the interaction between metal ions and corresponding ligands or the direct incorporation of as‐prepared metal‐based nanoparticles...
