Dataset for Synthetic DNA Fragments as Ultra-High-Resolution Multitracers to Quantify Transport Behavior of Micro- and Nanoplastics in Plant Systems
AI summary Read the abstract
Scientists developed a clever new tool that uses tiny, custom-made DNA tags to track exactly how microscopic plastic particles move through plants, from their roots up into stems and leaves. This matters because plants are a major pathway for plastic pollution to enter our food supply, and this precise tracking method could help researchers finally understand how much plastic ends up in the fruits and vegetables we eat. This dataset itself is mainly technical groundwork (testing the tool's accuracy and reliability), setting the stage for future studies on food safety and human exposure.
Raw data include standard curve construction, MNP size and zeta potential, encapsulation and extraction efficiencies, stability tests, FTIR, tissue uptake in hydroponic and sand culture, and plant dry weights.

Dataset for Synthetic DNA Fragments as Ultra-High-Resolution Multitracers to Quantify Transport Behavior of Micro- and Nanoplastics in Plant Systems
AI summary Read the abstract
Scientists developed a clever tracking tool, tiny synthetic DNA tags attached to micro- and nanoplastic particles, to precisely follow how these tiny plastic bits move into and through plants, from roots to leaves. This matters because plants are a major entry point for plastics into our food supply, and better tracking tools like this one help researchers figure out exactly how much plastic ends up in the foods we eat, which is a key step toward understanding potential risks to human health.
Synthetic DNA fragments as ultra-high-resolution multitracers to quantify transport behavior of micro- and nanoplastics in plant systems
AI summary Read the abstract
Scientists used a clever DNA-tagging trick to track exactly how tiny plastic particles move into lettuce plants, through water, air, and soil. They found that watering plants with plastic-contaminated water was the biggest source of contamination, and that smaller plastic particles (200 nanometers) traveled more easily into the edible leafy parts than larger ones, especially when plants "sweat" more (higher transpiration). This matters because it helps explain how microplastics end up in the food we eat, and suggests that both irrigation water quality and plant growing conditions could influence how much plastic ends up on our plates.
Multimodal imaging and quantification of lanthanide chelate-labeled micro- and nanoplastics in plants
AI summary Read the abstract
Scientists have developed a better way to track how tiny plastic particles move through plants—from roots to leaves—by using special glowing chemical tags that don't get washed out by the plant's natural background glow, unlike older tracking methods. This matters because microplastics in our food supply are a growing concern, and understanding exactly how they get into the crops we eat (like wheat and lettuce) is a key step toward figuring out whether—and how much—they end up on our dinner plates.
Tracing microplastics uptake and translocation in plants using aggregation-induced emission materials
AI summary Read the abstract
Scientists used special glow-in-the-dark materials to track how microplastics move through lettuce plants, from roots up to stems and leaves. This matters because it confirms plants can absorb and transport microplastics internally, meaning these tiny plastic particles could end up in the produce we eat, though the researchers note their method can't yet tell whether it's tracking whole plastic particles or just fragments that broke off. This new tracking tool could help future studies better understand exactly how much plastic ends up in our food.
Reproducible Data and R Code for a Meta-analysis and Machine-learning Study of Aged Micro- and Nanoplastic Phytotoxicity
AI summary Read the abstract
Scientists combined data from 51 studies to see how tiny plastic particles, especially ones broken down by sun and weather, affect plant growth. This resource itself is mainly a dataset and code for other researchers, but the underlying research helps us understand whether "aged" microplastics in soil are more or less harmful to crops than fresh ones, which matters since plants are part of how these particles could enter our food supply.
