Iron-based nanoparticles (FeNPs) demonstrate potential in alleviating Cd phytotoxicity; however, whether the response mechanisms vary from inside to outside the roots remains poorly understood. Here, Fe2O3 NPs-mediated mitigation of Cd toxicity in rice seedlings was investigated through root-exudate and root-metabolome analyses. FeNPs application enhanced plant growth by 47.01% and alleviated Cd-induced oxidative stress via modulation of antioxidant enzymes. Notably, FeNPs reshaped root exudation patterns under Cd stress, increasing low-molecular-weight organic acids by 20.9% but decreasing amino acids by 42.7% compared with the Cd-only treatment. Metabolomics profiles revealed that FeNPs differentially regulated endogenous metabolites: suppressing stress-associated malate accumulation by 6.99% while elevating gibberellin levels by 16.8–20.6% and upregulating arginine and glutamate metabolisms. The response of amino acids was more severe than that of organic acids, and arginine tended to accumulate and facilitate metabolism inside the roots. These findings provide novel insights into different response mechanisms in plant roots to nanoparticle application under heavy metal stress.

Encryption in Plasmonic Plastics

Just like weaving a delicate web in the world of light, utilizing the unique angle-chromaticity selectivity in super optical lattices, an all-encompassing information encryption platform is constructed. Information security is no longer a cold barrier, but a vibrant and colorful visual feast. More details can be found in article 2500231 by Shencheng Fu, Xintong Zhang, and co-workers.

Single-Nucleus Transcriptomics Reveals Prenatal and Postnatal Pb Exposure-Induced Cell-Specific Neurotoxicity and Dysregulated Microglia-Neuron Communication in Mice Brain

Xuting Liu, Chunfeng Huang, Mingyue Wang, Ligang Hu, Yang Song, Guibin Jiang

Lead (Pb) is an environmental pollutant that has lasting effects on neurodevelopment. Children exhibit heightened sensitivity to Pb exposure compared to adults, and prenatal Pb exposure can harm the developing fetal nervous system. However, the specific regulatory effects of Pb across various developmental stages are not well understood. This study employed single-nucleus RNA sequencing (snRNA-seq) to analyze mice brains at different ages (2 and 8 weeks) following prenatal and postnatal Pb exposure. Blood lead level in exposed mice is comparable to those detected in human samples, implying its environmental implication. A total of 43,303 brain cells were sequenced for cell-specific analysis. Pb exposure was found to elevate the proportion of immature neurons in the brains of 2 week-old mice and to perturb neurodevelopment- and neural structure-related pathways within neurons. In 8 week-old mice, Pb primarily influenced pathways implicated in synaptic transmission, signal transduction, and learning and memory in both neurons and glial cells. The communication involving neurotransmitters glutamate and γ-aminobutyric acid (GABA), along with their receptors, was disrupted between neuron

Modular Micromotor Fabrication with Self-Focusing Lithography

Qingxin Guo, Binglin Zeng, Yingnan Cao, Xiaofeng Li, Jingyuan Chen, Wei Wang, Jinyao Tang

Inside Back Cover

In article number 2401388, Zeng, Tang, and co-workers introduce a mass production method for micromotors featuring a particle-tip structure, achieved through self-focusing lithography induced by an array of TiO2 microspheres. By adjusting the tip composition, various capabilities such as photo-redox reaction-induced propulsion, fluorescent imaging, and electric and magnetic navigation are successfully demonstrated. Furthermore, the fabrication of double-tipped motors showcases the method's flexibility and potential for multifunctional combinations.
