Fate, toxicology and Organ-on-a-chip methodology of nanoplastics in human body
AI summary Read the abstract
Tiny plastic particles called nanoplastics can slip past the body's natural defenses—like the lining of your lungs, gut, and even the barrier protecting your brain—and travel through your bloodstream to reach vital organs. This review pulls together existing research on how this happens and the potential harm it could cause, especially to heart health, while also highlighting a promising lab tool (tiny chips that mimic human organs) that could help scientists study these risks more accurately than older test methods. The bottom line: we don't yet have all the answers on how dangerous nanoplastics are, but this new technology could help researchers find out faster and more reli
Nanoplastics (NPs) can cross the human biological barriers, enter the bloodstream, and accumulate in vital organs due to their unique physical and chemical properties. This review provides a detailed explanation of the mechanisms by which NPs cross the air-blood, intestinal, and blood-brain barriers. It provides more insight into how NPs interact with blood components after entering circulation, assesses the cardiovascular toxicity that results, and visually represents how NPs are distributed in human tissues. Traditional static models have significant limitations in simulating the complex physiological microenvironments of the human body. Organ-on-a-chip (OoC) technology is emerging as a novel toxicology tool due to its unique advantages in dynamically reconstructing the vascular microenvironment and biological barriers. This technology allows for a precise characterization of the hemodynamic behavior of NPs and their mechanisms of cross-barrier toxicity. In general, this work offers crucial theoretical and methodological insights to address existing technical issues in assessing the toxicity of emerging environmental contaminants.

A comparative review of organ-on-a-chip technologies for micro- and nanoplastics versus other environmental toxicants
AI summary Read the abstract
This review compares how organ-on-a-chip technology, which recreates miniature human organs on microchips, has been used to study the health effects of micro and nanoplastics versus other environmental toxins. These devices can simulate how plastic particles affect the lungs, liver, kidneys, and even the blood-brain barrier in ways that traditional cell and animal studies cannot. The technology offers a promising path toward better understanding how microplastics harm human organs without relying solely on animal experiments.

AI summary Read the abstract
This review paper summarizes existing research on how microplastics may affect human health, including the limits of current lab and animal studies. It discusses "organ-on-a-chip" devices, small lab systems using human cells grown in 3D, as a possible better way to study how microplastics interact with the body.
Health impacts of microplastic and nanoplastic exposure
AI summary Read the abstract
This review examines the growing evidence that micro- and nanoplastics can cross barriers in the lungs and gut, enter the bloodstream, and reach organs like the brain, placenta, and reproductive system. Early clinical studies suggest links to immune changes, heart problems, and reproductive effects, though more research is needed. Better methods for measuring plastic exposure in humans are critical to understanding the true health risks.
Lab-on-a-chip systems for microplastic and nanoplastic sampling, detection, characterization and bioassessment.

Tiny plastic particles called microplastics and nanoplastics are everywhere in our environment, but scientists still struggle to detect them and understand exactly how they affect our health. This paper reviews a promising technology—credit-card-sized "lab-on-a-chip" devices—that could make it much easier and faster to capture, identify, and test how these particles impact human cells and tissues. While this research doesn't reveal new health risks itself, it points toward better tools that could soon give us clearer, more reliable answers about whether the plastics in our food, water, and air are actually harming us.
Nano- and Microplastics in the Cardiovascular System: Current Insights and Biological Implications
AI summary Read the abstract
Tiny plastic particles from our environment—so small they can enter through the food we eat, the air we breathe, or even our skin—have been found lodged in heart and blood vessel tissue, and this review pulls together what scientists currently know about the damage they might cause, like inflammation, cell damage, and blood vessel problems that could contribute to heart disease. While researchers haven't yet proven these plastics directly cause heart disease in people, the growing evidence is concerning enough that the authors call for better tools to measure plastic exposure and more research into how to prevent harm. The bottom line: microplastics aren't just an environmental issue
