Data supporting "From Environmental Agglomerates to Membrane-Inserted Fragments: A Molecular Mechanism for Weathered Polyethylene Nanoplastics"
AI summary Read the abstract
Scientists used computer simulations to study how tiny, weathered plastic fragments (from breakdown of everyday polyethylene, like plastic bags) behave when they encounter cell membranes, the protective barrier around our cells. This is one piece of the puzzle in understanding whether and how nanoplastics might get inside our cells, which matters as researchers work to figure out what these increasingly common pollutants could mean for our health. Note that this particular dataset shares the technical simulation files and methods rather than reporting new findings on health effects directly.
This dataset contains representative simulation and analysis files supporting the molecular dynamics study “From Environmental Agglomerates to Membrane-Inserted Fragments: A Molecular Mechanism for Weathered Polyethylene Nanoplastics”. The deposited files document the workflow used for the constrained potential-of-mean-force calculations performed with the OCCAM hybrid particle-field molecular dynamics code. They include representative simulation input files, topology and connectivity information, center-of-mass constraint and force-output settings, the Fortran program used for block-averaging analysis of the constraint-force time series, representative block-averaging output, and the Fortran program used for numerical integration of the mean-force and associated standard-error profiles by the trapezoidal rule. A detailed description of the file structure and analysis workflow is provided in the accompanying README file. Additional methodological details, coarse-grained mappings, simulation parameters, and interaction parameters are reported in the Supporting Information of the associated manuscript.

AI summary Read the abstract
Scientists used computer simulations to study how tiny weathered plastic particles (from breakdown of everyday polyethylene, like plastic bags) behave when they encounter cell membranes, essentially modeling the physics of how these particles might break apart from clumps and embed themselves into living cells. This matters because understanding this molecular-level process helps researchers figure out whether and how nanoplastics could get inside our cells, which is a key step toward understanding potential health risks from plastic pollution. Note that this is a technical dataset supporting the simulation methods, not a study directly measuring health effects in humans or animals.

Scientists used computer simulations to study how tiny, weathered pieces of plastic (nanoplastics from breakdown of everyday polyethylene) interact with cell membranes at the molecular level, tracking how these plastic fragments move from clumped-up clusters to actually embedding themselves into membranes. This matters because understanding exactly how nanoplastics breach our cells could help explain how microplastic pollution might affect human health, though this study provides the technical simulation data and methods rather than new health conclusions.

Scientists used detailed computer simulations to study how tiny, weathered plastic particles (from breaking-down polyethylene, one of the most common plastics) behave when they encounter cell membranes, essentially modeling the step-by-step process of how these nanoplastics might break apart from clumps and embed themselves into our cells. This matters because understanding exactly how nanoplastics interact with membranes at a molecular level could help researchers figure out whether and how these ubiquitous plastic fragments might affect human cells, though this particular study focuses on the simulation methods themselves rather than drawing direct health conclusions.
Dynamics behavior of PE and PET oligomers in lipid bilayer simulations

Researchers used computer simulations to study how tiny plastic fragments from PET and polyethylene enter cell membranes, finding that small plastic molecules pass through with little resistance and can concentrate inside membranes — suggesting passive entry into cells is possible for nanoplastics just a few nanometers in size.
PE and PET oligomers’ interplay with membrane bilayers
AI summary Read the abstract
Researchers used computer simulations and lab membrane tests to study how small fragments of polyethylene (PE) and polyethylene terephthalate (PET) plastics interact with cell membranes, finding evidence that some tiny plastic molecules can passively diffuse through the membrane barrier into cells. This work suggests passive absorption — without any active transport — could be a key way nanoplastics enter human cells, with implications for understanding health risks from plastic exposure.
