ClearNanoparticles as catalysts of agricultural revolution: enhancing crop tolerance to abiotic stress: a review
This review looks at how nanoparticles can help crops withstand environmental stresses like drought, salt, and heavy metal contamination. While not directly about microplastics, the research is relevant because nanoparticles and microplastics share similar size ranges and behaviors in soil, and understanding how tiny particles interact with plants helps scientists assess both the risks and potential benefits of nanoscale materials in agriculture.
Applications of Titanium Dioxide (TiO2) Nanoparticles in Photocatalysis
This review examines the photocatalytic applications of titanium dioxide nanoparticles, which are widely used for breaking down environmental pollutants including microplastics through light-driven chemical reactions. Researchers discuss how different crystal phases and modifications of these nanoparticles enhance their ability to degrade organic contaminants. The study highlights the potential of titanium dioxide-based photocatalysis as an environmentally friendly technology for addressing persistent pollutants.
Carbon Nanostructures Decorated with Titania: Morphological Control and Applications
This review examines titanium dioxide nanostructures combined with carbon materials for applications in energy, environmental remediation, and antimicrobial surfaces.

Nanoparticles in Agriculture: Enhancing Crop Resilience and Productivity against Abiotic Stresses
This review examines how engineered nanoparticles can help crops withstand environmental stresses like drought, salinity, and heavy metal contamination. While not focused on microplastics directly, it discusses how nanotechnology interacts with similar biological pathways that microplastics disrupt in plants. The review also raises important concerns about the potential toxicity and environmental impact of adding more nanoparticles to agricultural systems.
Titanium dioxide nanoparticles alleviates polystyrene nanoplastics induced growth inhibition by modulating carbon and nitrogen metabolism via melatonin signaling in maize
Researchers found that titanium dioxide nanoparticles can help protect maize plants from the growth-inhibiting effects of polystyrene nanoplastics. The protective mechanism works through the plant hormone melatonin, which regulates carbon and nitrogen metabolism when the nanoparticles are present. The study suggests that certain nanoparticles could potentially be used as agricultural tools to help crops cope with nanoplastic contamination in soil.
Recent Findings in Adverse Effects of Tio2 NPs in Marine Algae and Zooplanktons: A Threat to Marine Ecosystems
This review summarizes recent findings on the harmful effects of titanium dioxide nanoparticles on marine algae and zooplankton. Researchers found that these nanoparticles can cause oxidative stress, DNA damage, and disruptions to cellular processes in marine organisms. The study highlights that TiO2 nanoparticles often interact with other pollutants like microplastics in marine environments, potentially amplifying their combined ecological impact.
TiO₂-based photocatalytic degradation of microplastics in water: Current status, challenges and future perspectives
This review examines how titanium dioxide-based materials can break down microplastics in water using light energy, generating reactive molecules that dismantle plastic polymer chains. While promising, the technology still faces challenges with efficiency and potential harmful byproducts, and more research is needed before it can be used at scale to clean microplastics from real-world water supplies.
How to improve crop photosynthesis more efficiently using nanomaterials: Lessons from a meta-analysis
Researchers analyzed dozens of studies and found that applying nanomaterials to crops can boost photosynthesis — the process plants use to grow — especially under drought and salt stress conditions, though they caution that lab results may not always translate to real farm fields and that nanoplastics in the soil can reduce these benefits.
Titanium dioxide nanoparticles enhance the detrimental effect of polystyrene nanoplastics on cell and plant physiology of Vicia lens (L.) Coss. & Germ. seedlings
Combined exposure of Vicia lens seedlings to polystyrene nanoplastics and titanium dioxide nanoparticles caused greater physiological and cellular damage than either contaminant alone, suggesting synergistic toxicity at the plant level.
Investigation of the efficiency of several TiO2 microstructures for the photocatalytic degradation of nanoplastics.
Researchers tested the efficiency of multiple titanium dioxide microstructures for photocatalytic degradation of nanoplastics in aquatic environments, addressing the growing problem of sub-micron plastic fragments in global water systems. TiO2-based photocatalysis showed varying effectiveness depending on catalyst structure and particle properties.
A Review on Crop Responses to Nanofertilizers for Mitigation of Multiple Environmental Stresses
This review examines how nanoscale fertilizers can help crops survive environmental stresses like drought, salt, and pollution by improving nutrient delivery at the cellular level. While focused on agricultural benefits, the research is relevant to microplastics because nanofertilizers may help plants cope with microplastic-contaminated soil. However, the authors caution that widespread use of nanoparticles in farming raises its own questions about potential effects on the environment and human health.
Promotion effect of nitrogen-doped functional carbon nanodots on the early growth stage of plants
Researchers found that nitrogen-doped carbon nanodots promoted seed germination, root growth, and biomass production across multiple plant species better than undoped nanodots. This is a plant science nanotechnology study not directly related to environmental microplastic pollution.
