Leonardo da Vinci Famous for its elaborate and nuanced artwork and advanced technical ideas. However, new research reveals another level of complexity in his drawings. It’s the hidden world of small life forms in his artwork.
Researchers say the findings could help build a “catalog” of microbiota for artwork. Each piece had a sufficiently unique collection of microorganisms that researchers would have been able to identify again later from their purely microbiology studies. The drawing microbiome is also sufficient to help researchers find counterfeit products based on microbiome differences, or find genuine drawings that have been stored under different conditions for centuries. There was an important element in common. Researchers have also shown that Da Vinci’s paintings have a significantly different microbiome than expected and are rich in bacterial and human DNA. There are also microorganisms that are known to degrade paper over time, showing why the efforts of their repairers were needed. This study is equivalent to a proof-of-concept exercise and shows that microorganisms may reveal or help unexpected history of certain artwork in the future. Detect counterfeiting.
Researchers have uncovered unexpected diversity by examining the microscopic biological material of living and dead in seven of Master’s “symbolic” drawings. Bacteria, Fungi And humans DNA.. Most of that material landed on sketches, probably even after Da Vinci’s death 501 years ago, so DNA (or at least most of it) wasn’t the polymath himself, but the other who had worked with drawings for centuries. It could be from people. However, the newly discovered biological material has a story to tell.
The biggest surprise the researchers wrote was the high concentration of bacteria in the drawings, especially compared to fungi. Previous studies have shown that fungi tend to dominate the microbiota of paper objects like these figures, but in this case an unusually large amount of bacteria from humans and insects (at some point). There was a fly that pooped on paper.

“Overall, insects, restoration workers, and geographic location all seem to leave invisible traces on the drawings,” the researchers say. Said in a statement.. “”[But] It’s hard to say if any of these pollutants have originated since Leonardo da Vinci was sketching the drawing. “
Most of that DNA could come from people who restored works that began in the 15th century. The team has not analyzed the genetic material at the level of detail needed to determine who specifically came from.
Researchers have used a new tool called nanopores. This is a gene sequencing method that quickly degrades and analyzes genetic material, and has conducted detailed research on various biological substances. The same researcher has studied the artistic microbiome in the past to find out how statues recovered from smugglers were stored while hidden. In the future, they said, this technique could reveal new details in the history of well-studied artwork.
This study was published in the journal on Friday (November 20th) Microbiology Frontier..
