Viruses in the era of microplastics and plastispheres: Analytical methods, advances and future directions
AI summary Read the abstract
This review examines how viruses interact with microplastics in the environment, including how viral particles attach to plastic surfaces and what this means for human and environmental health. Microplastics can carry viruses across water environments, and the biofilms that form on plastic surfaces create conditions for viral survival and gene transfer. These findings raise concerns that microplastics could serve as vehicles for spreading disease-causing viruses through water systems.
Research on microplastics and plastispheres now incorporates the study of viruses to evaluate their effects on the environment and human health. Sharing these new discoveries with the scientific community is crucial to fostering further research and collaborations. However, the current research and methodologies used are fragmented. To address this issue, this paper reviews the literature and the use of methodology developments in each study, identifying four emerging research areas: (1) viral interactions with microplastics; (2) viral population, diversity, and function in plastispheres; (3) the effects of viruses and plastic particles in host-associated environments; and (4) the impacts of viruses within plastispheres. To that end, the article is structured to streamline navigation and help readers easily access existing approaches, recent advancements, key findings, challenges, and opportunities in these areas. Our synthesis reveals that research methods include biochemical assays, omics techniques, spectroscopic analysis, and molecular and bioinformatic tools. Various mechanisms enable viruses to attach to microplastics and plastispheres, leading to widespread distribution and contributing to toxic effects and gene transfer. While the growing evidence is intriguing, there is still much to uncover about their ecological interactions, functions, and impacts.

Plastisphere-hosted viruses: A review of interactions, behavior, and effects
AI summary Read the abstract
This review examines how viruses attach to and thrive on microplastic surfaces in the environment, forming communities called the "plastisphere." These virus-laden microplastics can spread disease-causing agents through water and ecosystems, potentially reaching humans and posing public health risks that scientists are only beginning to understand.
Microplastics and viruses in the aquatic environment: a mini review
AI summary Read the abstract
This review summarizes what is currently known about how microplastics interact with viruses in aquatic environments. Researchers found that microplastics can serve as carriers for viruses, potentially influencing their persistence, transmission, and ability to cause infection in water systems. The evidence indicates that the growing presence of microplastics in waterways may create new pathways for viral spread that are not yet fully understood.
Microplastics as Vectors for Viral Transmission: Mechanisms, Influencing Factors, and Ecological-Health Risks
AI summary Read the abstract
Tiny plastic particles floating in the environment can stick to viruses and help them survive longer and spread more easily, which could increase the risk of getting sick. This review article summarizes what scientists have learned about how plastics and viruses interact, and why it matters, because many of us are now exposed to both microplastics and viruses at the same time, which could be worse for our immune systems than facing either threat alone. Understanding this problem better will help researchers figure out how to protect public health as plastic pollution continues to grow worldwide.
The potential role of micro- and nanoplastics in the spread of viruses
AI summary Read the abstract
This review examines how micro- and nanoplastics may act as vehicles that amplify the spread and infectivity of pathogenic viruses in humans and animals, explaining that the plastisphere (the microbial community living on plastic surfaces) can preserve viruses and that plastics weaken the body's natural barrier tissues. The authors warn that plastic particles carrying viruses could increase infection risk and potentially even help viruses develop new variants, calling for urgent interdisciplinary research.
Microplastics as emerging viral vectors: Nexus, mechanisms, ecological implications and health risks
AI summary Read the abstract
This review pulls together existing research showing that tiny plastic particles (microplastics) aren't just harmless debris—they can act like rafts that viruses cling to, helping them survive longer and travel farther in water, soil, and air than they would on their own. This matters because it means microplastics could potentially help spread infections more easily, though scientists still need more real-world studies to figure out exactly how big a risk this poses to human health.
