How do you depend the nanoplastics in your body? Leiden researchers revealed a method in Nature Protocols immediately that ought to make this simpler, and essential growth for each environmental and medication analysis.


From a molecular viewpoint, plastic is sort of just like natural materials. That makes it a troublesome substance to detect in dwelling beings. “Everything with carbon atoms is difficult to measure in organisms, so plastic too,” explains Martina Vijver, Professor of Ecotoxicology. “Animals and plants themselves consist largely of carbon. So, what are you measuring: the plastic or the organism itself?”

Detecting it in the proper means

The new method developed by Professors Martina Vijver and Willie Peijnenburg in cooperation with a consortium led by Dr. Fazel Monikh lifts a nook of this veil. By permitting nanoplastics to first take up steel, you possibly can then observe them far more simply. As lengthy as you observe them down once more in the proper means.

The article that was revealed immediately in Nature Protocols describes the alternative ways in which you could find the steel nanoplastics once more. “This allows you to see what happens to the nanoplastics after they have been absorbed,” says Vijver. “For example, which animals pick them up, or, which organs pick them up? And also, how many plastic particles do they pick up? You can then measure all that.”

The paper thus primarily describes the means in which this analysis may be accomplished. “It is actually a very dry paper to read,” Vijver laughs. “But it is important for scientists that we can use the same protocol. This way the different results are comparable.”

“We find it very logical to know where substances are in the environment,” says Vijver. “But we also need to know where they are in cells or organisms. Are they stored in the fatty parts, for example, or in the body fluids? With this method we can discover just that.”

And it isn’t solely ecologists who’re completely satisfied about this. Vijver: “This protocol is also very important for drug development. You can very easily use it to find out how well medicines arrive at the right place in the body.”
