Nano plastics are plastic particles smaller than 1,000 nanometers, 100 times smaller than human hair diameter, polluting the environment and food. They are now found in human blood, lungs, placents, and even breast milk..
Research on microplastics is still a relatively new field. In this blog post, we explore how scientists are investigating the effects of nanoparticles on the human brain and its defense.

Blood Brain Wall: Our Brain Defense System
The blood brain barrier (BBB) is a thin shield around the brain that protects from threats such as bacteria, toxins and chemicals. At the same time, barriers allow oxygen and nutrients to pass through small holes protected by specialized cells.
The nano plastics are so small that they can be taken through these defensive cells, known as Periches, to take nutrients to the brain. These ferris cells are mainly helped to maintain the brain -threatening barriers and clear toxins.
Potential connection of neuromodusal diseases
Diseases, such as Alzheimer’s and Parkinson’s bottles, are associated with dysfunction of Perichte cells, which questions whether small plastic sculptures or accumulation of these cells can bring about similar diseases. Scientists are investigating.
Nano plasticity research project
Plasticities have created their own particles similarly to being widely used in food containers and beverage bottles to study the potential effects of plastic particle exposure to pericytes.
The human brain, grown in the laboratory, was exposed to a chronic nano -forming particles of 31.25 times higher than normal detection in the blood for three or six days. This high level was used to replicate the potential exposure and accumulation of nano plastics in the BBB over time.
Since the nanoparticles are so small, we worked with the scientists of the Arts et metiers, Paris Institute of Technology and Glasgow University to monitor the concentration and molecular configuration of plastic particles in Pericytes.
The Fourier Conversion infrared spectroscopy, thermal weight analysis and differential injection calorie measurement (DSC) helps scientists to perform accurate measurements of microscopic water and temperature changes.
Then this measurement was then used to evaluate whether PET particles could cause oxidation stress. And whether the accumulation of this waste damages the mechanism of each cell that produces energy. The power of cells -mitochondria -and lack of energy means the deterioration of the death of the final cell and the deterioration of brain function.
Research results and future directions
This study showed that human paritate grew up in the laboratory was exposed to a high level of PET nano plastics for three days, slowing the mitochondrial function. Interestingly, it also showed the recovery of mitochondrial function from 6th to 10th exposure timeline test.
More research is needed to understand the overall scope of chronic exposure to PET nano -forming particles and the overall scope of mitochondrial recovery in human pericytes cells.
