ClearBiofilm on microplastics in aqueous environment: Physicochemical properties and environmental implications
This review examines how bacteria and other microorganisms form sticky films called biofilms on microplastic surfaces in water. These biofilms change how microplastics move through the environment and increase their ability to absorb pollutants like heavy metals, pesticides, and antibiotics. Biofilm-coated microplastics may also carry harmful bacteria, making them a greater potential health risk than clean microplastic particles.
Biofilm-Developed Microplastics As Vectors of Pollutants in Aquatic Environments
This review examines how biofilms that form on microplastics in aquatic environments change their ability to absorb and transport pollutants. Researchers found that biofilm-coated microplastics can absorb more contaminants than clean microplastics and serve as vectors that transfer both pollutants and potentially harmful microorganisms through aquatic ecosystems.
Biofilm formation and its implications on the properties and fate of microplastics in aquatic environments: A review
Researchers reviewed how microplastics in water attract and support communities of bacteria and other microorganisms that form biofilms — living coatings that alter the plastic particles' movement, help them carry pathogens, and affect how toxic chemicals attached to the plastic are absorbed by living things. Understanding this "plastisphere" ecosystem is critical for predicting where microplastics go and how harmful they become.
Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.
Microplastic-Associated Biofilms and Their Role in the Fate of Microplastics in Aquatic Environment
This review examines how microbial biofilms attached to microplastics in aquatic environments mediate the accumulation and transfer of chemical pollutants, exploring how the 'plastisphere' community influences the fate and ecotoxicological impact of microplastics and co-contaminants.
The Importance of Biofilms to the Fate and Effects of Microplastics
This review examines how biofilms — communities of microorganisms that form on microplastic surfaces — affect the fate and ecological effects of plastic pollution. Biofilm formation alters how microplastics are transported, ingested, and degraded in the environment, and the plastisphere can harbor pathogens and antibiotic-resistant bacteria that may pose risks to human health.
The role of microplastics biofilm in accumulation of trace metals in aquatic environments
This review examines how biofilms that form on microplastics in aquatic environments enhance the accumulation of trace metals from surrounding water. Researchers found that microorganisms colonizing plastic surfaces produce extracellular substances that facilitate metal sorption, effectively turning microplastics into concentrated carriers of metallic contaminants. The study highlights the dual pollution risk posed by microplastics serving as both physical pollutants and vehicles for toxic metal transport in waterways.
Environmental Health and Safety Implications of the Interplay Between Microplastics and the Residing Biofilm
This review examines the two-way relationship between microplastics and biofilms, the communities of microorganisms that quickly colonize plastic surfaces in the environment. Biofilms on microplastics can harbor harmful bacteria, concentrate toxic chemicals, and help spread antibiotic resistance genes through water systems. Understanding this interplay is important for human health because these contaminated biofilm-coated microplastics can enter drinking water and food supplies.
Exaggerated interaction of biofilm-developed microplastics and contaminants in aquatic environments
Researchers found that biofilm formation on microplastic surfaces exaggerates the adsorption and vector capacity for co-contaminants in aquatic environments, with biofilm-coated MPs showing substantially higher uptake of contaminants than pristine MPs.
Physicochemical behavior and ecological risk of biofilm-mediated microplastics in aquatic environments
This review explores how biofilm formation on microplastics in water environments changes their physical and chemical behavior, potentially increasing their ecological risks. Researchers found that biofilm-coated microplastics more readily absorb pollutants and antibiotic resistance genes, and may disrupt gut microbiota in organisms that ingest them. The findings suggest that the biological aging of microplastics in nature makes them more dangerous than freshly produced particles.
Recent advances in the relationships between biofilms and microplastics in natural environments
This review summarizes how microorganisms form biofilms on the surface of microplastics in water, changing the particles' physical properties and helping to spread bacteria and genes across ecosystems. These biofilm-coated microplastics can carry harmful microbes into new environments, raising concerns about waterborne disease transmission and the effectiveness of current water treatment methods.

Impact of Biofilm Formation on Microplastic Behaviour in Aquatic Environments: An Comprehensive Review.
This review examines how biofilms — communities of microorganisms that coat microplastics — change the behavior of plastic particles in aquatic environments, affecting how they move, sink, and interact with ecosystems. Understanding biofilm formation on microplastics is key to predicting where these particles end up and what risks they pose to water quality and aquatic life.
Research progress on the role of biofilm in heavy metals adsorption-desorption characteristics of microplastics: A review
This review examines how biofilm formation on microplastics in aquatic environments modifies their properties and changes how they adsorb and release heavy metals. Researchers found that biofilm-covered microplastics behave significantly differently than bare microplastics, which has important implications for understanding the combined environmental risks of microplastics and heavy metal contamination.
Biofilm formation on microplastics and interactions with antibiotics, antibiotic resistance genes and pathogens in aquatic environment
This review explains how microplastics in waterways develop bacterial biofilms on their surfaces that can harbor antibiotic-resistant bacteria and help spread antibiotic resistance genes to new environments. This is concerning for human health because these resistant microbes could eventually reach people through drinking water or seafood consumption.
Adsorption of heavy metals by biofilm-coated microplastics in aquatic environments: Mechanisms, isotherm and kinetic processes, and influencing factors
This review synthesizes research on how biofilms—microbial coatings that naturally form on microplastics in water—alter the particles' ability to absorb heavy metals like lead, copper, and cadmium, finding that biofilmed microplastics generally adsorb more metal than bare plastic and that electrostatic forces and surface complexation are the dominant mechanisms. This matters because microplastics coated in both biofilm and toxic metals may deliver a double dose of contamination to organisms that ingest them. The review identifies key gaps, including how competitive metal mixtures and shifting biofilm composition over time affect this combined pollution risk.
