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 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.
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 OCCAM simulation input and topology files, a representative constraint-force time series (forces.dat) obtained by concatenating the force outputs from successive simulation runs performed at the same fixed center-of-mass separation, the Fortran program used for block-averaging analysis, representative block-averaging output, and the Fortran program used for numerical integration of the mean-force and standard-error profiles using the trapezoidal rule. The PMF analysis uses the force 1-2 time series. A detailed description of the deposited files and analysis workflow is provided in the accompanying README file. Additional methodological details, coarse-grained mappings, system compositions, simulation parameters, and interaction parameters are reported in the Supporting Information of the associated manuscript.

AI summary Read the abstract
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.

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 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.
Molecular Insights into Nanoplastic Incorporation in Lipid Bilayers: Theory, Simulation and Experiment
AI summary Read the abstract
Scientists used computer simulations and lab experiments to study how tiny plastic fragments (nanoplastics) get into our cells by slipping into the fatty membranes that surround them. They found that small plastic chains can easily wedge into these membranes, especially if bits of plastic "stick out" from larger nanoparticles like tiny anchors—suggesting this may be a key first step in how plastic pollution actually invades our cells and tissues. This matters because as microplastics and nanoplastics become more common in our environment, understanding exactly how they breach our cells could help scientists figure out what health risks they might pose.
Effects of polyethylene microplastics on cell membranes: A combined study of experiments and molecular dynamics simulations
AI summary Read the abstract
Researchers combined laboratory experiments with molecular dynamics simulations to study how polyethylene microplastics interact with cell membranes. They found that nanoscale plastic particles can penetrate and disrupt cell membrane structure, causing leakage and potentially leading to cell damage. The study provides a detailed molecular-level understanding of one of the fundamental ways microplastics may harm living cells.
