When Protective Mechanisms Fail
The human body has barriers – lungs, placenta, and the blood-brain barrier – designed to repel harmful substances. However, nanoplastic particles, smaller than 1 µm, can penetrate these protective walls.
A 2024 study (Translocation of Nanoplastics Across Biological Barriers, Nature Nanotechnology) showed that particles as small as 100 nm can enter the bloodstream from the lungs within a few hours.
Similarly, a study in Environment International (2023) found plastic fragments in human placental tissue – an indication that maternal exposure can directly transfer to the fetus.
In the Brain – and Beyond
Once nanoplastics are in the bloodstream, they can also cross the blood-brain barrier – a barrier long considered almost impenetrable.
A study by the University of New Mexico Health Sciences (2025) (Microplastics in Human Brain Tissue) found plastic fragments in brain tissue at concentrations 50% higher than ten years ago – particularly in people with neurodegenerative diseases.
These particles cause oxidative stress, neuroinflammation, and cellular damage – processes associated with cognitive decline and neurotoxicity.
Invisible Threat – Visible Solutions
Due to their small size, nanoplastic particles evade both the body's natural protective mechanisms and conventional water filtration systems.
SYDROS develops next-generation high-performance filter media that specifically bind micro- and nanoplastics, PFAS, and plastic-related chemicals at a molecular level – for true water purity and sustainable health protection.
The threat is invisible – the solution is clear.
